SCHMETZ 135X17 SERV 7/DPX17 SERV 7 SIZE 140/22 INDUSTRIAL SEWING MACHINE NEEDLES

chmetz 135x17 SERV 7 Size 140 (NM 140 / Size 22) Industrial Sewing Machine Needles – Pack of 10

Tackle heavy fabrics, stretch materials, and elastic textiles with ease using this pack of 10 Schmetz 135x17 SERV 7 industrial sewing machine needles, compatible with DPx17 SERV 7 systems. Designed for industrial lockstitch sewing machines, these chrome-coated needles feature advanced reinforcement and a hump scarf design that prevents skipped stitches, improves stitch accuracy, and extends needle life — even during high-speed production.

Needle Point – STANDARD (Normal Round Point)

The Standard (Normal Round Point) features a slim, conical tip that provides smooth fabric penetration for a wide range of materials. It delivers strong, consistent stitches without damaging fibres, making it ideal for both woven and stretch fabrics.

Schmetz SERV 7 – Reinforced Design for Heavy-Duty Sewing

The Schmetz SERV 7 system is specially developed to reduce fabric damage and skipped stitches, particularly when sewing elastic or heavy materials. Its reinforced blade (15–20% stronger) and hump scarf create a larger thread loop that improves hook pick-up, enhances stitch consistency, and prevents needle deflection.

This design allows for the use of a smaller needle size without compromising stability, resulting in tighter stitches, reduced hole size, and longer machine life.

Key Benefits:

• Prevents skipped stitches on elastic and heavy fabrics

• Reinforced blade increases strength and reduces bending

• Chrome coating provides durability and smoother operation

• Produces cleaner seams and smaller stitch holes

• Ideal for high-speed industrial sewing environments
