Sewing Machine Needles 135x17 are high quality, round point needles. The most common needle type, these Groz-Beckert needles can be used for all general sewing. These industrial needles feature a sharp point and completely round shanks with no burrs. Burrs on needle shanks can be problematic and cause separation of threads and skipped stitches. Needle sizes are listed two ways, by size and measurement, so a #20 needle is the same as a 125. For more information on needle and thread choices, please email us here.
