HEICO-LOCK® Wedge Lock Washers

Check up to five results to perform an action.


The self-loosening of bolted joints is one of the most commonly occuring failure modes in the operation of machines and systems. HEICO-LOCK® Wedge Lock Washers prevent loosening of the bolted joint by providing a safe and reliable bolt securing system - even for extremes of vibration or dynamic loads.

Features:

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