Schmetz B27 BLUK Size 100 Industrial Sewing Machine Needles (Teflon Coated) – Pack of 10 

The Schmetz B27 BLUK Size 100 (NM 100 / Size 16) industrial sewing machine needles were engineered for chainstitch machine.

These needles feature the standard round point (R), a slim and conical design ideal for versatile sewing applications. The standout feature of the BLUK variant was its Teflon-coated, non-stick surface applied over a roughened, phosphorated base. This innovation helped prevent the accumulation of melted synthetic residues, keeping the needle cleaner for longer compared to standard chrome-coated models.

As a result, skipped stitches and thread breakage were greatly reduced, ensuring smoother sewing performance and extended needle life. While production has ceased, the Schmetz BLUK needles remain notable for their specialist role in sewing synthetic and coated materials.
