HEICO-LOCK®
Wedge Lock Washers

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.

• Certified system for securing bolts, working at low and high preload levels
• Particularly suitable for dynamic loads – including when using lubricants
• Can be re-used
• Very easy to install and remove (wedge lock washers are supplied as a pre-assembled pair)
