The Schmetz 16X231 SERV 7 Size 90 industrial sewing needles are built for superior stability and seam quality, especially when sewing elastic or stretch fabrics. The unique SERV 7 design features a reinforced blade for extra strength and a hump scarf that forms a larger thread loop, making it easier for the hook to catch the thread and reduce skipped stitches.

With 15–20% added blade reinforcement, these needles are less likely to bend or break under heavy use. They also help minimise stitch holes while improving fabric displacement, making them a trusted choice for professional sewing applications.

Key Features:

• Reinforced SERV 7 Design – 15–20% stronger blade for maximum stability.

• Hump Scarf – Enlarges thread loop for more reliable stitch formation.

• Skip-Stitch Prevention – Designed specifically for sewing elastic and stretch fabrics.
