HEICO-LOCK® washers are a paradigm shift in locking fastener technology. Conventional fasteners often rely on the physics of friction instead tension to maintain clamp load. Hence nylon insert nuts, metal lock nuts, split lock washers, safety-wire, thread adhesives, etc. offer limited performance.
Known as “wedge-lock,” “cam-lock,” or “wedge washers,” the unique tension based design of the washer system provides superior resistance to constant vibration, high dynamic loads and thermal cycling.
Bolt loosening results in both washer halves separating under the bolt head, resulting in an increase in tension and clamp load. During removal, only the cam surfaces move, resulting in low off torque force.
