HEICO-LOCK Wedge Lock Washer Standard - Steel

The HEICO-LOCK® Wedge Lock Washer (Standard Series) in steel is engineered for secure fastening of bolted joints subjected to vibration, dynamic loading, and mechanical stress. The system utilizes a dual-washer wedge-locking principle, where precision-formed cam faces generate increased clamping force under loosening torque, ensuring preload retention independent of friction. Radial serrations mechanically embed into mating surfaces to prevent rotational back-off and maintain joint integrity under service conditions.

​

Manufactured from high-strength steel with corrosion-resistant surface treatment, each washer is produced to controlled dimensional tolerances in accordance with recognized fastening standards. Supplied as pre-assembled pairs and organized within a durable, compartmentalized storage case, the assortment enables efficient identification, rapid selection, and reliable on-site application. Full dimensional specifications are provided below the product image to support accurate engineering selection and installation compliance.

Even under extremes of vibration or dynamic loads, the HEICO-LOCK® Wedge Locking System provides maximum reliability.

​

When the bolt is tightened, the external radial teeth of the HEICO-LOCK® Wedge Lock System embed themselves in an interlocking fashion with the respective mating surface.

​

If the securing system is subject to dynamic stress, movement is only possible between the internal washer surfaces. This results in an increase in the clamping force.

​
