Contact SupplierThe 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 forcen Certified system for securing bolts, working at low and high preload levels
