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

DBx1 SES SERV 7, 16x231 SES SERV 7 are SCHMETZ industrial sewing machine needles for sewing knitwear, jersey, and sportswear. They combine the slightly rounded SES ball point with the reinforced SERV 7 design, helping reduce both damage to the material’s threads and the risk of skipped stitches.

SES Point and SERV 7 Design Features

SES (Light Ball Point) has a slightly rounded ball point that helps push knit loops and material threads aside rather than cutting through them. This point is particularly suitable for fine and medium-weight knits.

SERV 7 features a special needle geometry with a reinforced working area and Hump Scarf design. It forms a larger thread loop, improves stitch formation reliability, and reduces the risk of needle deflection, including when sewing stretch materials and cross seams.

Suitable Materials and Applications

• Fine and medium-weight knits.
• Jersey fabrics.
• Knitted sportswear.
• Lightweight denim.
• Stretch knits and suitable textile laminates.
• Joining layers of material and sewing cross seams.
• Sewing with stretch threads when consistent stitch formation is important.

Compatibility and Needle Selection

These needles are designed for industrial sewing machines that use the DBx1 or 16x231 system. Before purchasing, check your sewing machine manual and choose an NM size suitable for the material and thread.

Recommendation: For heavier knits and thicker denim, compare SES SERV 7 with SUK SERV 7. The SES point is generally more suitable for materials with a fine knit structure.
