Autobar 8mm Nylock Nuts 4 Pack 4 Pack

Autobar 248 8mm Nylock Nuts 4 PackA nylock nut, which is also referred to as a nyloc or self-locking nut, has a ring of nylon moulded into the top of the nut. As the bolt threads through, the nylon grips the thread tightly, adding friction that resists the nut working loose under vibration. This differs from a standard hex nut, which relies only on thread tension and can gradually loosen on a component that is prone to vibrations when in use.This pack contains four 8mm nylock nuts, also referred to as M8 by their metric thread designation. Once fitted, the nylon insert means the nut is harder to remove than a standard nut, and it is best practice to fit a new nylock nut each time rather than reusing one, since the nylon can lose some of its grip after repeated use. They are ideal for fixing points that see vibration, such as engine mounts, brackets, or panels, where a standard nut might work loose over time.
