Buttonhole & Bartack Machine Needle for Zigzag, Pattern & Double-Needle Lockstitch Machines

Best for workshops running buttonhole, bartack, zigzag, button-sewing, programmable pattern, or double-needle lockstitch machines — not for walking-foot machines, which use a different needle system.

Why This Needle

Buttonhole and pattern-sewing machines need a needle built for their specific feed mechanism, and using the wrong system causes skipped stitches that tension adjustments won’t fix. This needle is stocked genuine across four trusted brands and a wide Nm 70–140 size range, so one listing covers most of what a buttonhole and bartack workshop needs.

Features

• Genuine stock in four brands: Groz-Beckert, Schmetz, Organ, Flying Tiger
• Wide size range from Nm 70 to Nm 140
• Also sold as 135×5, 134, DPx7, and SY 1955 on some machine charts and catalogs
• Suited to zigzag, bartack, buttonhole, button-sewing, programmable pattern, and double-needle lockstitch machines

उपयोग के मामले

• Buttonhole stitching on shirts, trousers, and garments
• Bartack reinforcement points (belt loops, pocket corners)
• Zigzag and decorative pattern stitching
• Button attaching and double-needle lockstitch work

फ़ायदे

• Matching this needle system (not a walking-foot needle) to your machine avoids the skipped-stitch problem that tension adjustment alone can’t fix
• Four brand options in one listing means you’re not stuck waiting on a single supplier
• Wide size range covers light shirting through heavier workwear fabric

Specs

How to Fit This Needle

First, confirm your machine is a buttonhole, bartack, zigzag, pattern, or double-needle lockstitch type — this needle is not built for walking-foot machines. Next, loosen the needle clamp screw and remove the old needle, noting its orientation. Then, insert the new needle to the correct depth as per your machine manual. Finally, tighten the clamp screw and run a test stitch on scrap fabric before production.

पूछे जाने वाले प्रश्न

Will this needle work on my walking-foot machine?

No. This needle system is built for buttonhole, bartack, zigzag, button, pattern, and double-needle lockstitch machines — walking-foot machines use a different needle system, and fitting this one causes skipped stitches that tension adjustment won’t fix. Check your machine’s manual before ordering.

What other names is this needle sold under?

This needle system is also listed as 135×5, 134, DPx7, and SY 1955 on some machine charts and supplier catalogs — it’s the same needle, so check the specs table above if your machine manual uses a different code.

Which size should I use?

Sizes run from Nm 70 (fine, for light shirting and fine fabric) up to Nm 140 (heavy, for thicker workwear and multi-layer bartack points). Match the size to your fabric weight — too fine a needle on heavy fabric bends or breaks, too heavy a needle on light fabric leaves visible holes.

How many needles come in one pack?

Each pack contains 10 needles, giving you a working stock for ongoing buttonhole and bartack production without reordering constantly.
