HEICO-LOCK® Wedge Locking Systems

Bolted joints in machines, vehicles, aircraft or ships are usually impacted by heavy dynamic loads or vibration and therefore tend to self-loosen. The loosening is a gradual process that often remains undetected until damage or total failure occurs. HEICO-LOCK® Wedge Locking Systems offer effective and sustainable protection – for every mission-critical application.

The HEICO-LOCK® series is a two-washer bolt locking system based on the wedge locking principle. When tensioning, the radial ribs on the outer surface of the washer pairs imprint into the surface of the components, while the opposing wedges at the inner surfaces effectively prevent self-loosening of the bolt.

The portfolio features a wide range of innovative bolt-locking solutions and intelligent product combinations designed to make bolt securing fast, simple, and effective:
