Here HEICO Befestigungstechnik GmbH, located in Ense-Niederense, Germany, explains how its HEICO-LOCK ring lock washers provide high-quality, user-friendly bolt securing for the most demanding applications and are ideal for repeated use.
The ring locking system on HEICO-LOCK ring lock washers 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.
Design of the ring locking system
HEICO-LOCK ring lock washers are supplied pre-assembled. The ring locking system consists of a polyamide ring (PA) and the already familiar HEICO-LOCK wedge lock washers.
The wedge lock washers secure the bolted connections reliably and the ring permanently holds the two single washers together in the correct position (figure one).
