Detail & Specs
Prevailing torque flange nuts prevent against vibration loosening. 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.
The reduced 12mm wrench size allows installation in space restricted areas.
This type of all-metal lock nut can have a conical shape with an elliptical deformation or a flat top 3-punch locking design, 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.
Zinc Plated and Yellow Zinc Plated finishes provide corrosion resistance without sacrificing strength.
