Detail & Specs
Prevailing torque flange nuts prevent against vibration loosening, a small wrench size allows installation in space restricted areas.
The design of this all metal lock 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.
This all-metal lock nut has a conical shape with an elliptical deformation, meant to distort the threads of the mating bolt or screw. The smooth bottom flange acts as a built-in washer to evenly distribute force over a larger area against the fastening surface.
Also known as all metal lock nut, distorted thread hex flange nut, prevailing torque nut, stover flange nut.
Materials & Finishes
Class 8 metric locking flange nuts provide a medium strength, high tensile fastening solution. Commonly paired with Class 8.8 bolts and screws.
The Black Zinc Plated finish provides corrosion resistance without sacrificing strength.
