Variants
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)
Function:
Highly secure locking as wedge surfaces slope up between the two lock washers. The screw connection is locked by pretension instead of by friction.
Advantages:
- Quick and easy installation/removal with standard tools
- Secure locking even with lubrication
- 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)
