The Singer Ball Point Sewing Machine Needles (2045) are specialized tools designed to make sewing synthetics and stretch fabrics simple and efficient. Unlike universal needles, these feature a medium, slightly rounded tip that passes between fabric threads rather than piercing them, preventing damage to spandex, interlocks, and other stretch knits. Engineered for performance, the 2045 series addresses common sewing frustrations by eliminating skipped stitches and inconsistent stitch quality. This is achieved through a slightly smaller shank, which brings the needle's scarf closer to the sewing machine hook point for a more precise catch. This specific Size 100/16 needle is tailored for heavier weight fabrics, providing the necessary strength and penetration for coarse or heavy knits. Whether you are working with thick synthetic blends or heavy-duty stretch materials, these needles ensure even, professional results. Designed for versatility, these needles are compatible with all makes of home sewing machines. They provide a reliable solution for makers who need to maintain the integrity of their stretch fabrics while achieving a high-quality, durable seam.
