Socket Head M3 Lock Nut

A Socket Head M3 Lock Nut is a secure fastening component designed to be used with M3 (3 mm) bolts or socket head screws. It is specially made to prevent loosening due to vibration, movement, or repeated use. Lock nuts often include a nylon insert (nyloc) or a deformed thread design that creates extra friction, ensuring a strong and stable hold. These nuts are widely used in machinery, robotics, automotive parts, electronics, and precision assemblies where reliable fastening is essential. Made from steel or stainless steel, an M3 lock nut provides durability, long-lasting performance, and improved safety in mechanical joints.
