General:


Original Nord-Lock wedge lock washers secure screw connections that are subject to severe vibrations and dynamic loads.


Corrosion resistance:


High level of corrosion resistance (at least 1,000 hours in salt spray test in accordance with ISO 9227)

  • Reliable securing - even for screw connections with short clamping lengths

  • Reusable (depending on operating environment)

  • CE marking

  • Laser marking for continuous traceability
