Used on engine mount bolts and other bolts where a lock nut is advised
Galling occurs during fitting when pressure and friction cause the bolt thread to seize to the thread of a nut or tapped hole.
This is also known as "cold welding- friction weld".
Special anti-seizing or anti-galling lubricants need to be used.
Each pack of fine picth Nyloc nuts we send will have a small pack of copper slip to reduce the chance of galling
