Even under extremes of vibration or dynamic loads, the

HEICO-LOCK® Wedge Locking System provides maximum reliability.

​

When the bolt is tightened, the external radial teeth of the HEICO-LOCK® Wedge Lock System 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 clamping force.

​
