₹125.00
Best for garment units running flatlock and interlock machines on knit fabric — T-shirts, innerwear, and stretch garments needing a clean, flat seam finish.
Why This Needle
Flatlock and interlock machines need a needle with an RG (ball) point built for knit fabric — a needle meant for wovens tends to snag or pierce knit loops instead of sliding between them. This needle is genuine Groz-Beckert stock in the standard flat-seamer size range, so you can match it to your fabric weight without guessing.

How to Fit This Needle
First, match needle size to your fabric weight — 09/65 for fine knits, 14/90 for heavier stretch fabric. Next, loosen the needle clamp screw on your flatlock or interlock machine and remove the old needle, noting its orientation. Then, insert the new needle fully into the clamp per your machine’s manual. Finally, tighten the clamp screw and run a test seam on scrap knit fabric before production.
FAQs
What’s the difference between this and a regular overlock needle?
This needle has an RG (ball) point built specifically for knit fabric, which slides between knit loops instead of piercing them. A regular round-point needle meant for wovens can snag knit fabric and cause skipped stitches on a flatlock seam.
What other names is this needle sold under?
This needle system is also listed as UYX121GS, DVx1, 62×2, and MY1001 on some needle 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?
For fine knits and lightweight stretch fabric, 09/65 or 11/75 works well. For heavier knit fabric, move up to 14/90. Too fine a needle on heavier fabric can bend; too heavy a needle on fine knits leaves visible holes.
Will this fit my flatlock machine brand?
This is a standard flat-seamer needle system, but we haven’t verified fit on a specific machine brand. Check your machine’s manual for the needle system code (UY121GS, DVx1, or the others listed above) before ordering.
