HAx1SP Overlock Needle Size 75/11 are super stretch needles with a medium ball point. HAx1SP overlock needles are suitable for all types of knit fabrics. The HAx1SP overlock needles have a special flat shank that prevents skipped stitches even on tightly elastic fabrics and a wider and shorter eye that lets you use thicker sewing threads.
The Super Stretch needle can be used in all domestic machines that require needle system 130/705H as well as some overlock machines. Please check your machine manual for needle type. Machines should specify HAx1SP system or 130/705H.
