Whether you are a tailor, boutique owner, garment manufacturer, embroidery operator, textile production unit, alteration professional, or home sewing enthusiast, selecting the correct needle is essential for achieving clean, consistent, and professional stitching results.\r\n\r\nMany sewing problems that are blamed on thread, machine settings, or machine quality are actually caused by using an incorrect, worn, bent, or damaged needle. Skipped stitches, thread breakage, seam puckering, uneven stitching, fabric damage, and poor embroidery quality can often be solved simply by choosing the right sewing machine needle.\r\n\r\nThis category includes a wide range of sewing machine needles, industrial sewing needles, tailoring machine needles, silai machine needles, textile sewing needles, garment sewing needles, Organ needles, lockstitch machine needles, overlock machine needles, embroidery machine needles, high-speed sewing needles, and universal sewing needles used across various sewing industries.\r\n<h2>Types of Sewing Machine Needles<\/h2>\r\nDifferent sewing machines require different needle systems. Even when two needles look identical, they may not be interchangeable \u2014 always check the system number before ordering.\r\n<h3>Lockstitch Machine Needles \u2013 DBx1<\/h3>\r\n<a href=\"https:\/\/stitchpartner.com\/product\/dbx1-golden-needle-for-lock-stitch-machine\/\">DBx1 needles<\/a> are among the most commonly used industrial sewing needles and are the standard system for single-needle lockstitch machines. They are widely used in tailoring shops, garment factories, boutiques, alteration centers, and textile manufacturing units, and are compatible across industrial machines from Jack, Juki, Brother, Zoje, Typical, and Siruba. Suitable for tailoring, garment manufacturing, general stitching, and fashion production.\r\n<h3>Heavy-Duty Industrial Needles \u2013 DPx5<\/h3>\r\n<a href=\"https:\/\/stitchpartner.com\/product\/dpx5-needle-button-hole-machine\/\">DPx5 needles<\/a> are designed for heavier sewing operations involving thicker materials and larger thread sizes. Common uses include denim manufacturing, upholstery work, canvas stitching, bag manufacturing, technical textiles, and leather goods production.\r\n<h3>Overlock Machine Needles \u2013 DCx27 \/ B27<\/h3>\r\n<a href=\"https:\/\/stitchpartner.com\/product\/dcx27-b27-81x1-for-overlock-sewing-machine\/\">DCx27 and B27 needles<\/a> are used for seam finishing, knitwear production, garment assembly, and edge overlocking operations across several industrial overlock machine models. They're built to withstand continuous high-speed operation in overlock and safety-stitch machines.\r\n<h3>Embroidery Machine Needles<\/h3>\r\nEmbroidery machine needles are specifically designed for decorative stitching and computerized embroidery applications. They reduce thread friction, improve embroidery quality, prevent thread breakage, and maintain stitch consistency during high-speed embroidery. Units producing logos, monograms, uniforms, and decorative garments generally rely on specialized embroidery needle systems rather than standard lockstitch needles.\r\n<h3>Interlock &amp; Flatlock Needles \u2013 UY128<\/h3>\r\n<a href=\"https:\/\/stitchpartner.com\/product\/tvx3-uyx128-704962-sewing-machine-needle\/\">UY128 needles<\/a> are used in interlock and coverstitch machines handling knitwear, hosiery, sportswear, and stretch fabrics, and are engineered for high-speed production while minimizing fabric damage.\r\n<h2>How to Choose the Correct Sewing Machine Needle<\/h2>\r\nMany buyers select needles based only on size, but professional garment factories usually weigh several factors before choosing a needle.\r\n<h3>Machine Type<\/h3>\r\nThe needle system must match the machine specification \u2014 size alone doesn't guarantee compatibility.\r\n<h3>Fabric Type<\/h3>\r\nDifferent fabrics require different needle sizes and point types.\r\n<h3>Thread Size<\/h3>\r\nThe needle eye must allow smooth thread movement without excessive friction.\r\n<h3>Sewing Speed<\/h3>\r\nHigh-speed industrial machines require needles rated for continuous high-speed operation.\r\n<h3>Application<\/h3>\r\nEmbroidery, tailoring, denim production, leather stitching, knitwear manufacturing, and upholstery work all call for different needle characteristics.\r\n<h2>Needle Size Guide<\/h2>\r\nNeedle size selection affects both stitch quality and fabric protection. Using a needle that's too small can cause thread breakage, while one that's too large may damage fabric and leave visible needle holes.\r\n<h3>Size 9\u201311<\/h3>\r\nSuitable for chiffon, silk, lightweight fabrics, and other delicate materials.\r\n<h3>Size 14\u201316<\/h3>\r\nSuitable for cotton fabrics, general garment stitching, shirts, dresses, and uniforms.\r\n<h3>Size 18\u201321<\/h3>\r\nSuitable for denim, heavy cotton, workwear, and jackets.\r\n<h3>Size 22\u201325<\/h3>\r\nSuitable for canvas, leather, upholstery materials, and industrial textiles.\r\n<h2>Needle Numbering &amp; Specifications<\/h2>\r\nNeedle sizes are usually printed as two numbers, such as 80\/12 or 100\/16 \u2014 the first is the metric (Nm) size, measured as the blade diameter in hundredths of a millimeter above the needle's eye, and the second is the older Singer\/imperial size still used on many Indian machine manuals. A \"60\/8\" needle is thinner and suited to lightweight fabrics; a \"120\/19\" is thicker and meant for heavy material. Matching this number to your fabric weight matters as much as matching the needle system itself.\r\n\r\nApproximate length and shank diameter for the needle systems most commonly asked about by our customers, compiled from published cross-reference data (<a href=\"https:\/\/ismacs.net\/needle_and_shank\/pdfs\/NeedleXRef9-30-23.pdf\" target=\"_blank\" rel=\"nofollow noopener\">ISMACS International<\/a>) \u2014 always confirm against your machine manual before ordering, since shank diameter can vary slightly by needle manufacturer:\r\n<table>\r\n<thead>\r\n<tr>\r\n<th>Needle System<\/th>\r\n<th>Length to Point<\/th>\r\n<th>Shank Diameter<\/th>\r\n<th>Typical Nm Range<\/th>\r\n<th>Used On<\/th>\r\n<\/tr>\r\n<\/thead>\r\n<tbody>\r\n<tr>\r\n<td>DBx1<\/td>\r\n<td>~38.2 mm<\/td>\r\n<td>1.63 mm (Nm 65\u2013110); 2.00 mm above Nm 110*<\/td>\r\n<td>Nm 65\u2013110<\/td>\r\n<td>Single-needle lockstitch<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>DPx5 (135x7)<\/td>\r\n<td>~38.6 mm<\/td>\r\n<td>2.00 mm<\/td>\r\n<td>Nm 70\u2013140<\/td>\r\n<td>Heavy-duty lockstitch, zigzag, buttonhole<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>DPx17 (135x17)<\/td>\r\n<td>~43.8 mm<\/td>\r\n<td>2.00 mm<\/td>\r\n<td>Nm 90\u2013160<\/td>\r\n<td>Heavy lockstitch, walking-foot machines<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>DCx27 \/ B27<\/td>\r\n<td>~33.4 mm<\/td>\r\n<td>2.02 mm<\/td>\r\n<td>Nm 65\u2013120<\/td>\r\n<td>Overlock, safety-stitch<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>UY128GAS<\/td>\r\n<td>~44.6 mm<\/td>\r\n<td>2.00 mm<\/td>\r\n<td>Nm 65\u2013130<\/td>\r\n<td>Interlock, coverstitch, flatlock<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>TVx7<\/td>\r\n<td>~42.6 mm<\/td>\r\n<td>2.00 mm<\/td>\r\n<td>\u2014<\/td>\r\n<td>Chainstitch machines<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>EBx1 (490\/860)<\/td>\r\n<td>~31.1 mm<\/td>\r\n<td>2.02 mm<\/td>\r\n<td>\u2014<\/td>\r\n<td>Quilting machines<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>DVx57<\/td>\r\n<td>~44.0 mm<\/td>\r\n<td>2.00 mm<\/td>\r\n<td>\u2014<\/td>\r\n<td>Feed-off-arm machines<\/td>\r\n<\/tr>\r\n<tr>\r\n<td><a href=\"https:\/\/stitchpartner.com\/product\/bora-silai-machine-ki-sui\/\">DRx2<\/a> (124x2, UY1973)<\/td>\r\n<td>\u2014<\/td>\r\n<td>\u2014<\/td>\r\n<td>Nm 200\u2013250<\/td>\r\n<td>Bag-closing machines (jute\/woven poly bags)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td><a href=\"https:\/\/stitchpartner.com\/product\/tq-1-button-machine-ki-sui\/\">TQx1<\/a> (175x1, 1935)<\/td>\r\n<td>\u2014<\/td>\r\n<td>\u2014<\/td>\r\n<td>Nm 65\u2013140<\/td>\r\n<td>Button-sewing machines<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>TQx7 (2091, 175x7)<\/td>\r\n<td>\u2014<\/td>\r\n<td>\u2014<\/td>\r\n<td>Nm 80\u2013140<\/td>\r\n<td>Button-sewing machines (round shank)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td><a href=\"https:\/\/stitchpartner.com\/product\/tv-64-feed-off-arm-machine-needle\/\">TVx64<\/a> (B64, UY192GLS)<\/td>\r\n<td>\u2014<\/td>\r\n<td>\u2014<\/td>\r\n<td>around Nm 100<\/td>\r\n<td>Feed-off-arm machines on knits\/stretch fabrics (ball point)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td><a href=\"https:\/\/stitchpartner.com\/product\/side-munda-silai-machine-ki-sui\/\">TVx5<\/a> (149x5, 62x45)<\/td>\r\n<td>\u2014<\/td>\r\n<td>\u2014<\/td>\r\n<td>Nm 80\u2013140<\/td>\r\n<td>Feed-off-arm and belt-loop machines<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>UOx154 (UY154GAS, 151x21)<\/td>\r\n<td>\u2014<\/td>\r\n<td>\u2014<\/td>\r\n<td>Nm 60\u2013140<\/td>\r\n<td>Curved-needle overlock\/serger machines (e.g. Union Special 39500 class)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>UOx113 (UYx113GS, 2055)<\/td>\r\n<td>\u2014<\/td>\r\n<td>\u2014<\/td>\r\n<td>Nm 60\u2013140<\/td>\r\n<td>Multi-needle elastic and tape-attaching machines<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nNote: DRx2, TQx1, TQx7, TVx64, TVx5, UOx154, and UOx113 are specialised systems used on specific machine types (bag closers, button sewers, feed-off-arm and multi-needle elastic machines) rather than general lockstitch or overlock machines, so length-to-point and shank diameter weren't consistently published across our sources for these \u2014 we've left those columns blank rather than guess. We stock DRx2, TQx1, TVx64, and TVx5 as regular items; TQx7, UOx154, and UOx113 are less commonly requested but can be sourced on request.\r\n\r\n*DBx1 shank diameter is the one figure that genuinely differs by brand \u2014 roughly 1.63 mm on Schmetz\/MUVA-spec needles versus about 1.59 mm on Organ-spec needles, which is why a needle that \"should\" fit sometimes sits loose or tight in the clamp. If in doubt, bring your old needle in or send us a photo of the marking and we'll confirm before you order.\r\n<h2>Needle Point Types and Their Importance<\/h2>\r\nMost buyers understand needle size but overlook needle point design. Professional textile manufacturers often choose needles based on point type rather than size alone, since the wrong point can damage fabric even at the correct size.\r\n<h3>R Point<\/h3>\r\nA standard round point suited to woven fabrics and general stitching applications.\r\n<h3>SES Point<\/h3>\r\nA light ball point suited to lightweight knitted fabrics and fine, densely woven garments.\r\n<h3>SUK Point<\/h3>\r\nA medium ball point that separates fibers rather than piercing them aggressively \u2014 suited to knitwear, stretch fabrics, hosiery, sportswear, and medium-to-coarse denim.\r\n<h3>SPI Point<\/h3>\r\nSuited to fine, densely woven fabrics and premium garment production, where a straighter stitch helps minimize seam pucker.\r\n<h3>LR Point<\/h3>\r\nCuts the material at a slight angle, making it popular for leather stitching and decorative seams.\r\n<h2>Common Needle Selection Mistakes<\/h2>\r\nMany sewing issues occur because buyers make avoidable needle selection mistakes.\r\n<h3>Using the Wrong Needle System<\/h3>\r\nA DBx1 needle cannot replace every industrial needle system. Always verify compatibility before purchasing.\r\n<h3>Using Worn Needles<\/h3>\r\nEven a small bend can affect stitch formation and damage fabric.\r\n<h3>Ignoring Fabric Type<\/h3>\r\nA needle suitable for denim may damage lightweight fabrics.\r\n<h3>Using Incorrect Needle Size<\/h3>\r\nImproper sizing often causes thread breakage and uneven stitching.\r\n<h2>Why Thread Breakage Happens<\/h2>\r\nThread breakage is one of the most common sewing complaints. Possible causes include a damaged needle eye, a bent needle, incorrect needle size, an incorrect needle system, the wrong thread-to-needle combination, excessive machine speed, or poor threading. In many cases, replacing the needle immediately solves the problem.\r\n<h2>Organ Needles and Professional Needle Brands<\/h2>\r\nOrgan Needle is one of the most respected names in the global sewing industry, widely used by garment factories, embroidery units, textile manufacturers, and professional tailoring operations. Other brands industrial users commonly recognize include Groz-Beckert and Schmetz, which also produce specialized sewing machine needles for industrial applications.\r\n\r\nStitchPartner is an authorised dealer for Organ, Groz-Beckert, and Orange needles \u2014 so what ships from us is sourced through the manufacturer's own distribution channel, not repacked or grey-market stock.\r\n<h3>Groz-Beckert<\/h3>\r\nGroz-Beckert is a family-owned German manufacturer founded in 1852 and headquartered in Albstadt, with 15 production sites worldwide (including a plant in India) and over 170 years in precision needle manufacturing. Its sewing needle range \u2014 built on more than 40 years of dedicated sewing-needle production \u2014 covers clothing needles for lockstitch, flat-seam, blind-stitch and button sewing, leather needles with cutting points, technical-textile needles, and single- and multi-head embroidery needles, including its SAN\u2122 special-application series for fine fabrics and denim. Groz-Beckert needles are known for consistent point geometry and coating durability, which matters most on high-speed factory floors running long shifts.\r\n<h3>Orange Needles (Taewon Needle Ltd.)<\/h3>\r\nOrange is the needle brand of Taewon Needle Ltd., a South Korea\u2013based manufacturer headquartered in Busan. Orange-brand needles are a widely used replacement option across lockstitch, overlock, and heavy-duty needle systems \u2014 including DPx17\/135x17, the system stocked in our <a href=\"https:\/\/stitchpartner.com\/product\/dpx17-135x17-sewing-machine\/\">DPx17\/135x17<\/a> listing \u2014 and are a common choice among factories that want a dependable needle at a lower cost than the premium European brands.\r\n<h3>Flying Tiger<\/h3>\r\nFlying Tiger needles are manufactured by Jiangsu Flying Tiger Needle Industry Co., Ltd., a China-based, ISO14001-certified needle manufacturer founded in 2009 that exports across Asia, Europe, the Americas, Africa, and the Middle East. Flying Tiger needles cover the same common industrial systems \u2014 DBx1, TVx7, and similar \u2014 and are typically positioned as a budget-friendly alternative for high-volume, cost-sensitive production runs. We are not an authorised Flying Tiger dealer; if you specifically need Flying Tiger-branded stock, ask us before ordering and we'll confirm availability.\r\n<h2>Which Sewing Machine Needle Fits My Machine?<\/h2>\r\nOne of the most common questions buyers ask is about compatibility. Needle compatibility depends primarily on the needle system rather than the machine brand alone \u2014 industrial sewing machines from brands such as <a href=\"https:\/\/stitchpartner.com\/product-category\/jack-sewing-machine-spare-parts\/\">Jack<\/a>, <a href=\"https:\/\/stitchpartner.com\/product-category\/juki-sewing-machine-spare-parts\/\">Juki<\/a>, <a href=\"https:\/\/stitchpartner.com\/product-category\/brother-sewing-machine-spare-parts\/\">Brother<\/a>, <a href=\"https:\/\/stitchpartner.com\/product-category\/siruba-sewing-machine-spare-parts\/\">Siruba<\/a>, <a href=\"https:\/\/stitchpartner.com\/product-category\/pegasus-sewing-machine-spare-parts\/\">Pegasus<\/a>, Zoje, Typical, <a href=\"https:\/\/stitchpartner.com\/product-category\/kansai-sewing-machine-spare-parts\/\">Kansai Special<\/a>, and Yamato may use different needle systems depending on the machine model. Always verify your existing needle system before ordering a replacement.\r\n<h3>Jack Machine Models &amp; Their Needle Systems<\/h3>\r\nSince Jack is one of the most common industrial machine brands in Indian factories, here's the needle system for a few widely used Jack models, taken from Jack's own published machine specifications:\r\n<table>\r\n<thead>\r\n<tr>\r\n<th>Jack Model<\/th>\r\n<th>Machine Type<\/th>\r\n<th>Needle System<\/th>\r\n<\/tr>\r\n<\/thead>\r\n<tbody>\r\n<tr>\r\n<td>Jack F4<\/td>\r\n<td>Single-needle direct-drive lockstitch<\/td>\r\n<td>DBx1 (#11\u201318)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Jack A2B-C<\/td>\r\n<td>Single-needle lockstitch with undertrimmer<\/td>\r\n<td>DBx1 (#11\u201318)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Jack T1790GS<\/td>\r\n<td>Direct-drive buttonhole machine<\/td>\r\n<td>DPx5 (#12)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Jack C6-4<\/td>\r\n<td>Double-needle overlock (4-thread)<\/td>\r\n<td>DCx27 (#11)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Jack W4S<\/td>\r\n<td>Interlock \/ flat-bed<\/td>\r\n<td>UY128GAS<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nThis isn't exhaustive \u2014 Jack's range runs to dozens of models, and even within one machine family the needle can change by variant.

Always match the needle system recommended for your machine.\r\n<h3>What is the difference between DBx1 and DPx5 needles?<\/h3>\r\nDBx1 needles are generally used in lockstitch sewing machines, while DPx5 needles are designed for heavier-duty sewing applications involving thicker materials and larger threads.\r\n<h3>Are Organ needles suitable for industrial sewing machines?<\/h3>\r\nYes. Organ needles are widely used in industrial sewing machines, embroidery machines, overlock machines, and garment manufacturing facilities worldwide.\r\n<h3>How often should sewing machine needles be replaced?<\/h3>\r\nNeedles should be replaced whenever they become dull, bent, damaged, or when stitch quality starts to decline.\r\n<h3>Can one needle fit all sewing machines?<\/h3>\r\nNo. Different machines require different needle systems. Always verify compatibility before purchasing.\r\n<h3>What causes skipped stitches?<\/h3>\r\nSkipped stitches are commonly caused by worn needles, incorrect needle systems, damaged needle points, or improper needle installation.\r\n<h3>Which needle is best for embroidery machines?<\/h3>\r\nEmbroidery machine needles are specifically designed for embroidery applications and generally provide better thread performance during decorative stitching.\r\n<h3>Which needle point is best for stretch fabric?<\/h3>\r\nSUK point needles are commonly recommended for knitwear, sportswear, stretch fabrics, and hosiery because they help reduce fabric damage and improve stitch quality.\r\n<h3>Which sewing machine needle is best for denim?<\/h3>\r\nHeavier needle sizes combined with suitable industrial needle systems are generally preferred for denim and heavy fabric sewing applications.\r\n<h3>How do I identify the correct replacement needle?<\/h3>\r\nCheck the needle system marked on your existing needle packet, machine manual, or machine specification plate before ordering a replacement.\r\n<h3>What does a needle number like 80\/12 or 60\/8 mean?<\/h3>\r\nThe first number is the metric (Nm) size \u2014 the needle's blade diameter in hundredths of a millimeter \u2014 and the second is the older imperial size for the same needle. A 60\/8 is a fine needle for lightweight fabrics like chiffon or silk, while a 120\/19 or higher is a thick needle for denim, canvas, or leather.\r\n<h3>Do you supply sewing machine needles in bulk or wholesale?<\/h3>\r\nYes. Alongside single packs, we supply bulk and wholesale quantities for garment factories, embroidery units, and production houses across India, with GST billing and pan-India delivery. Contact us with your needle system and quantity for volume pricing.\r\n<h3>What needle sizes work on an industrial overlock machine?<\/h3>\r\nMost industrial overlock machines use the DCx27\/B27 needle system in sizes roughly Nm 65 to 120, with the exact size chosen by fabric weight \u2014 finer sizes (around Nm 65\u201380) for lightweight knits, and heavier sizes (Nm 90 and up) for medium-to-heavy fabrics. Always confirm your machine's needle system before ordering, since not all overlock models use DCx27\/B27.","parent":0,"count":24,"filter":"raw","image":""}],"product_tag":[{"term_id":3786,"name":"135x5","slug":"135x5","term_group":0,"term_taxonomy_id":3786,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3788,"name":"bartack needle","slug":"bartack-needle","term_group":0,"term_taxonomy_id":3788,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3787,"name":"buttonhole machine needle","slug":"buttonhole-machine-needle","term_group":0,"term_taxonomy_id":3787,"taxonomy":"product_tag","description":"","parent":0,"count":2,"filter":"raw","image":""},{"term_id":3785,"name":"DPx5","slug":"dpx5","term_group":0,"term_taxonomy_id":3785,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3789,"name":"Organ needle","slug":"organ-needle","term_group":0,"term_taxonomy_id":3789,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3790,"name":"Schmetz needle","slug":"schmetz-needle","term_group":0,"term_taxonomy_id":3790,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Buttonhole &amp; Bartack Machine Needle | Stitch Partner<\/title>\n<meta name=\"description\" content=\"Genuine needle for buttonhole, bartack, zigzag &amp; double-needle lockstitch machines.
