The Schmetz 16X231 SERV 7 Size 100 industrial sewing needles are specially engineered to eliminate skipped stitches and fabric damage, particularly when sewing elastic or stretch materials. Their unique SERV 7 design includes a reinforced blade for up to 20% more stability and a hump scarf that creates a larger loop of thread, making it easier for the hook to catch the thread consistently.

These needles are highly stable, resistant to bending, and ensure smooth sewing performance even under demanding industrial use. By displacing fabric effectively, they allow the use of a smaller needle size without loss of strength, producing smaller stitch holes and cleaner seams.

Key Features:

• Reinforced SERV 7 Blade – Up to 20% stronger, reducing bending and breakage.

• Hump Scarf Technology – Improves loop formation and reduces skipped stitches.

• Elastic & Stretch Fabric Performance – Designed for trouble-free sewing on challenging materials.
