Collection: Metric Set Screws

Metric set screws, also called grub screws, have no head, so they sit flush inside a threaded hole to lock pulleys, gears, collars and knobs onto a shaft. We carry M2 to M12 in lengths from 3 mm to 60 mm, in black oxide alloy steel and A2-70 stainless, with cup, cone, dog, knurled cup and nylon tip points.
