Nylock Nut

1. These nuts incorporate a special moulded Nylon Insert, the internal diameter of which is smaller by a predetermined degree than the bolt thread.

2. The tightening of the bolt forces the leading threads of the bolt into the Nylon insert which yields under this pressure to form a thread.

3. Due to the resistance applied by the nylon insert the working sides of the nut and bolt threads are in close contact and create friction. “Friction” which builds up, is maintained on the entire length of the sides of the nut and bolt threads which normally carry the load when the nut is fully tightened.

4. The Nyloc nut is locked and made completely vibration proof by two independent forces :

a) The close contact and friction set up and maintained between the entire length of the working face of the threads, due to the encircling “Wedge” effect of the Nylon insert.

b) The Nylon insert being highly compressed “grips” the bolt threads with a sustained and considerable inward pressure.
