The Ultimate High–Performance Anti–Vibration Locking Washer!

HEICO LOCK - WEDGE LOCK WASHERS

The 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 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 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 without any reduction in functio or quality

  • 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 such as Inconel and SMO are available upon request

  • Available from M3 - M42 abd 1/4" - 1" - custom sizes upon request

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 surface on the inside of the lock washers, radial teeth on the outside

  • Interlocking embedding of the radial teeth with the respective mating surface (when the bolt is tightened

  • System movement only possible between the inside washer suraces, allowing the securing system to readjust itself automatically

  • Increase in clamping force
