SCHMETZ 134-35 SD1 SERV 7/2134-35 SD1 SERV 7/DPX35 SD1 SERV 7 SIZE 140/22 INDUSTRIAL SEWING MACHINE NEEDLES

Schmetz 134-35 SD1 SERV 7 Size 140 (NM 140 / Size 22) Industrial Sewing Machine Needles – Pack of 10

Enhance your industrial sewing performance with this pack of 10 Schmetz 134-35 SD1 SERV 7 needles, also known as 2134-35 SD1 SERV 7 or DPx35 SD1 SERV 7. Designed for precision stitching and superior stability, these premium industrial sewing machine needles combine the SD1 point (round point with a small triangular tip) with Schmetz SERV 7 reinforcement for clean, professional-quality seams.

SD1 Point – Round Point with Small Triangular Tip

The SD1 point features a fine triangular incision that cuts approximately 10% of the stitch hole, while the remaining 90% is displaced by the conical round point “R.”
This produces straight, tidy seams and a refined stitch appearance with smaller perforations compared to standard cutting points — ideal for detailed, high-quality sewing.

Perfect for:

• Medium to heavy woven fabrics

• Applications requiring precise, clean stitch lines

• Decorative stitching and topstitching on dense materials

SERV 7 Technology – Reinforced for Strength and Stability

The Schmetz SERV 7 needle series is specially engineered to combat skipped stitches and needle bending during high-speed sewing.
The hump scarf design creates a larger thread loop, helping the hook catch the thread more efficiently, while the reinforced blade provides up to 20% extra stability.
This allows the use of a smaller needle size without compromising strength — reducing needle deflection, fabric damage, and machine wear.
