The HEICO-LOCK® wedge locking system delivers high quality anti-vibration security
for the most demanding of bolted joint applications.
Even under extremes of vibration or dynamic loads, HEICO-LOCK® wedge lock washers provide maximum reliability. When the bolt is tightened, the external radial teeth of the HEICO-LOCK® wedge lock washers embed themselves in an interlocking fashion with the respective mating surface.
If the securing system is subject to dynamic stress, movement is only possible between the internal washer surfaces. This results in an increase in the preload force.
