The Schmetz 16X231 SERV 7 Size 70 industrial sewing needles are specially engineered to reduce fabric damage and eliminate skipped stitches, particularly when sewing elastic or stretch materials. Featuring a hump scarf that produces a larger loop of thread and a reinforced blade for added strength, these needles offer outstanding stability, reduced bending, and excellent stitch reliability.

This unique SERV 7 design often allows the use of a needle one size smaller without compromising stability, resulting in smaller stitch holes and optimised fabric displacement. Perfect for lockstitch sewing applications where precision and durability are essential.

Key Features:

• Special SERV 7 Design – Reinforced blade (+15–20%) for high stability and reduced breakage.

• Hump Scarf – Forms a larger thread loop for more reliable hook catching and fewer skipped stitches.

• Ideal for Elastic & Stretch Fabrics – Designed to tackle problems common with elastic materials.

• Durable Chrome Coating – Extends working life and performance.

• Industrial Lockstitch System – Compatible with multiple needle designations.
