DBx1 SERV 7, 16x231 SERV 7 — SCHMETZ universal industrial sewing machine needles, 10 pcs.

DBx1 SERV 7, 16x231 SERV 7 are SCHMETZ universal industrial sewing machine needles with a reinforced SERV 7 design and a standard R-type round point. They are intended for sewing a range of woven fabrics and suitable technical textiles, especially where greater needle stability and reliable stitch formation are required.

SERV 7 technology features

SCHMETZ SERV 7 features a special needle geometry with a reinforced working section and a specially shaped indentation near the needle eye (Hump Scarf). This design helps form a larger needle thread loop, which the sewing machine hook can catch more easily.

The reinforced working section reduces needle deflection, helps prevent skipped stitches, and lowers the risk of needle breakage when sewing challenging materials and multiple layers.

Suitable materials and applications

• Lightweight and medium-weight woven fabrics.
• Densely woven fabrics and technical textiles.
• Seams joining layers of different fabrics.
• Materials with varying numbers of layers and cross seams.
• Coated and laminated materials suitable for an R-type round point.
• Sewing tasks where needle stability and fewer skipped stitches are important.
