Golden-Coated Needle for Jack, Juki, Brother & Other Lockstitch Machines

Best for workshops running single-needle lockstitch machines on denim, cotton, polyester, and blended fabric — a titanium-nitride coated needle built to resist heat and wear on continuous factory runs.

औद्योगिक उपयोग के लिए यह सुई क्यों विशिष्ट है?

Industrial setups demand both speed and precision. This needle’s Gebedur gold-titanium coating minimizes heat buildup and friction, letting fabric glide smoothly under the presser foot. It reduces skipped stitches and thread breakage, which improves overall productivity. Because of its versatile design, it works reliably on denim, cotton, polyester, and blends, making it suitable for a wide range of projects.

How to Fit This Needle

First, match needle size to your fabric — Nm 100 for standard cotton and light blends, Nm 160 for heavier denim. Next, loosen the needle clamp screw on your lockstitch machine and remove the old needle, noting the shank orientation. Then, insert the new needle to the correct depth per your machine’s manual. Finally, tighten the clamp screw and run a test seam on scrap fabric before production.

पूछे जाने वाले प्रश्न

What makes the gold coating different from a regular needle?

The gold color comes from Gebedur, a titanium-nitride coating that reduces friction and heat buildup during continuous stitching. This means the needle stays sharp longer under factory-speed use than an uncoated needle, cutting down on how often you need to replace it.

Will this needle fit my Jack machine model?

Yes, if your machine is a Jack F4, A2, A2B, A2C, A4, A5, A6F, A6F-D, A6F-E, or A6F-H — these are all confirmed compatible. It’s also a standard fit across other single-needle lockstitch brands including Juki, Brother, Zoje, Typical, and Siruba.

Why does this needle sometimes feel loose or tight in my clamp?

Shank diameter for DBx1-system needles varies slightly by manufacturer — roughly 1.63mm on Schmetz/MUVA-spec needles versus about 1.59mm on Organ-spec needles. If a needle feels off in your clamp, this small manufacturing difference is usually why, not a wrong or damaged needle.

Which size should I use for denim vs. lighter fabric?

For standard cotton and light blends, Nm 100 (size 16) is the usual choice. For heavier denim and thicker fabric, move up to Nm 160 (size 23). Nm 110 (size 18) sits in between for mid-weight jobs.
