Functional Principle

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
