Functional Principle

HEICO-LOCK^® Wedge locking system

An important feature of HEICO-LOCK ^® Wedge Lock Washers, setting them apart from other systems that are available, is the securing of the bolt fastening using preload force rather than friction

Wedge-shaped cams on the inside of the lock washers, radial teeth on the outside
Interlocking embedding of the radial teeth with the respective mating surface
(when tightening the bolted joint)
System movement only possible between the inner wedge shaped cams.
Movement across these wedge shaped surfaces effectively self locks the bolt
Increase in clamping force
