HEICO-ONE Safety-Washer

Product catalog summary

Introduction
The HEICO-ONE Safety-Washer is an innovative backup washer designed for use with HEICO-LOCK® Reaction Washers. It is specifically engineered to prevent the bolt or nut from turning on the passive side during the tightening process of large bolted joints.

Design and Function
The washer features wave-shaped locking ribs on both sides, creating a positive friction/form fit even with low preload forces. It is placed on the passive side between the bolt head/nut and the clamped part bearing surface, allowing for pre-assembly in difficult-to-access areas. This design eliminates the need for additional counter-holding measures or a second person during assembly.
