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

Advantages:
- Quick and easy installation/removal with standard tools
- Secure locking even with lubrication
- High level of corrosion resistance
- Reliable securing - even for screw connections with short clamping lengths
- Reusable (depending on operating environment)
- CE marking
- Laser marking for continuous traceability
- Designed for screws up to and including strength class 12.9 (steel) and A4-80 (high-grade steel)
