Zenith 5/16" zinc plated nyloc nuts give you a reliable, vibration-resistant lock for everyday assembly jobs. The integrated nylon insert grips the bolt thread to stop the nut backing off under movement, so fixings stay tight without extra thread locker.
Ideal for securing brackets, furniture, speaker and TV mounts, and general fittings where you want fasteners to hold firm. The zinc plating suits indoor use and areas not exposed to direct weather.

They are 5/16" imperial nyloc nuts, supplied in a pack of 15.
A nylon collar inside the nut grips the bolt thread, creating friction that resists loosening from vibration and movement.
Zinc plated steel hardware with a silver finish, suited to indoor use and areas not exposed to direct weather.
