Nord-Lock Washers

Nord-Lock Washers

Nord-Lock has been focusing on providing the world's most effective bolt securing system for over 30 years. Their products are based on leading wedge-locking technology and are recongnized for their ability to safely secure joints exposed to severe vibration and dynamic loads.

Nord-Lock secures bolted joints with tension instead of friction. The system is comprised of a pair of washers that has cams on one side and radial teeth on the opposite side. Since the cam angle "α" is greater than the thread pitch "B" a wedge effect is created by the cams, preventing the bolt from rotating loose.

Nord-Lock Washers provide more than just a safe locking function, using Nord-Lock products also improves the general performance of a bolted joint.

Product Features and Benefits:

  • Maintains high clamp load and thereby ensures the function of the joint
  • Quick and easy to install and remove with standard tools
  • Locking function not affected by lubrication
  • Defined and uniform friction conditions which result in a more accurate preload
  • Same temperature characteristics as standard bolt / nut
  • Reusable - in addition, Nord-Lock washers do not affect the reusability of fasteners
  • The washers are hardened and can support and distribute great loads
  • High corrosion resistance
  • Can be used with fasteners up to grade 12.9 (ASTM A574)
  • Reliable locking, even for joints with short clamp length
  • Secures fasteners at both high and low preloads
  • No retightening needed
  • Verifiable locking function
  • Elegant solution and problem solving - modern engineering
