Tri-Lock Nut, Galvanized

Tri Lock style lock nuts are all metal prevailing torque lock nuts with a conical top and a flat bottom bearing surface with chamfered corners. The thread distortion on the top thread of the nut makes it frictionally resistant to rotation. Dimensional specifications are governed by ASME B18.2.2. Available in galvanized finish for corrosion resistance.
