    An important feature of the HEICO-LOCK® wedge locking systems, 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
