DBx1 SUK SERV 7, 16x231 SUK — SCHMETZ industrial sewing machine needles for knitwear and denim, 10 pcs.

DBx1 SUK SERV 7, 16x231 SUK SERV 7 are SCHMETZ industrial sewing machine needles for knitwear, denim, and coarser-structured textiles. They combine the medium ball point of SUK with the reinforced SERV 7 design, helping reduce damage to material threads, skipped stitches, and the risk of needle deflection.

SUK Point and SERV 7 Design Features

SUK (Medium Ball Point) has a medium-rounded ball point. It is more rounded than SES and helps push apart coarser knit loops and textile threads.

SERV 7 features special needle geometry with a reinforced blade and Hump Scarf design. It helps form a larger thread loop and reduces needle deflection when sewing thicker materials, multiple layers, and cross seams.

• Medium-weight and heavy denim.
• Stonewashed denim.
• Sandwashed denim.
• Corsets and corset-style garments.
