The Nylock Nut 4mm Stainless Steel is a high-quality and reliable nut that can secure your fasteners and prevent them from vibrating or loosening. The nut has a nylon insert that acts as a locking mechanism, which grips the threads of the bolt or screw and creates friction. The nylon insert also deforms slightly to conform to the shape of the threads, which increases the contact area and the holding power.

It has a size of 4mm, which means that it can fit with bolts or screws that have a diameter of 4mm and a thread pitch of 0.7mm.
