Top Lock Flange Nuts

Top Lock Flange Nuts

Top-Lock Prevailing torque flange nuts prevent against loosening by providing resistance when tightened down on a bolt thread. The friction between the nut threads and the bolt increases the amount of force needed to securely lock the assembly into place.

The smooth bottom flange acts as a built-in washer to evenly distribute force over a larger area against the fastening surface.
