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)
- Also suitable for high-tensile bolts of 8.8, 10.9 and 12.9 and their respective nuts
- Available in steel or stainless steel with narrow or wide bearing surfaces – other materials are available upon request
- Available from M3 – M76 and ¼” – 3” - custom sizes upon request

TECHNICAL INFORMATION
Functional Principle
HEICO-LOCK® Wedge locking system
An important feature of HEICO-LOCK® Wedge Lock Washers, 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
