European Copper Exhaust Nut with Conical Top
A copper plated finish makes these locking nuts suitable for extreme heat automotive and motorsport applications, such as exhaust manifolds. Temperature degree range: - 94 to 750 Fahrenheit

Prevailing torque hex nuts prevent against loosening due to vibration. This type of all-metal lock nut has a conical shape with an elliptical deformation that is meant to distort the threads of the mating bolt or screw.

The design of this all metal nut provides resistance when tightened down on a bolt thread. The friction between the threads of the nut and the bolt increases the amount of force needed to tighten (and securely lock) the assembly into place.

Also known as all metic metal lock nut, distorted thread hex nut, prevailing torque nut, stover nut.
