Nord-Lock Washer

Advanced Bolt Security with Wedge-Locking Technology

Ensure ultimate bolt security with our Nord-Lock Washers, designed using patented wedge-locking technology that prevents loosening due to vibration and dynamic loads. Trusted across industries like construction, automotive, heavy machinery, and wind energy, these washers guarantee safe, secure, and maintenance-free bolted joints.

  • Wedge-Locking Principle: Uses tension, not friction, to secure bolted joints – ensuring unmatched resistance to vibration.

  • Reusable Design: Can be used multiple times without loss of performance, reducing total cost of ownership.

  • Pre-Assembled Pair: Each washer set comes as a glued pair for easy and precise installation.

  • High Performance Under Load: Maintains bolt tension even in extreme vibration or dynamic conditions.

  • Available for All Bolt Grades: Works with standard, high-strength, and stainless bolts.
