HEICO-LOCK® Ring Lock Washers provide high-quality, user-friendly bolt securing for the most demanding of applications and are ideal for repeated use. The ring locking system guarantees that the two wedge lock washers are always fastened in the correct position with the wedge shaped cams on the inside and the radial teeth on the outside. This means that the bolt locking system is always easy, safe and quick to install, even for non-specialist users.
