SCHMETZ 135X17 SERV 7/DPX17 SERV 7 SIZE 130/21 INDUSTRIAL SEWING MACHINE NEEDLES

Schmetz 135x17 SERV 7 Size 130 (NM 130 / Size 21) Industrial Sewing Machine Needles – Pack of 10

Sew heavy, elastic, or tightly woven materials with precision using this pack of 10 Schmetz 135x17 SERV 7 industrial sewing machine needles, compatible with DPx17 SERV 7 systems. Engineered for industrial lockstitch sewing machines, these chrome-coated needles offer superior stability, accuracy, and reduced skipped stitches — even under high-speed conditions.

Needle Point – STANDARD (Normal Round Point)

The Standard (Normal Round Point) features a slim, conical shape that penetrates fabric smoothly without causing damage. It’s ideal for a wide range of sewing applications on woven, stretch, and heavy fabrics.

Schmetz SERV 7 – Designed for Stability and Skip Stitch Prevention

The Schmetz SERV 7 needle is specially designed to address two common sewing issues — fabric damage and skipped stitches, especially when sewing elastic or stretch materials. With a reinforced blade (15–20% stronger) and a hump scarf, this needle produces a larger thread loop for reliable stitch formation and enhanced stability.

This innovative design allows for the use of a smaller needle size while maintaining strength, helping to reduce stitch hole size, optimise fabric displacement, and protect machine components from wear or damage.

Key Benefits:

• Prevents skipped stitches on elastic and stretch materials

• Reinforced blade for up to 20% more needle strength

• Reduces needle bending and breakage

• Chrome coating provides durability and smooth performance

• Suitable for high-speed industrial sewing applications
