ACUTE ROUND POINT "SPI"

Schmetz 135x17 SPI Industrial Sewing Machine Needles – Acute Round Point 

Crafted by Schmetz, the 135x17 SPI industrial sewing machine needles—also known as DPx17 SPI—are engineered for precision stitching on densely woven and coated materials. These needles feature the SPI (Acute Round Point), a very slim point designed for clean, accurate fabric penetration without puckering.

Whether you're stitching shirt collars, cuffs, or fine garments from silk or taffeta, the SPI point shape delivers consistent results and optimal seam appearance, even on thin or slippery materials. These needles are also suitable for handling non-covered elastomeric threads and the manufacture of fur garments and skins.
