General:


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


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

  • 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)

Certificates and approvals:


  • DIBt (Deutsches Institut für Bautechnik - German Institute for Construction Technology)

  • DNV GL (Det Norske Veritas Germanischer Lloyd)

  • EBA (Eisenbahn-Bundesamt - German Federal Railway Authority)

  • TÜV (Technischer Überwachungs-Verein - German Technical Inspection Association)

  • LR (Lloyd's Register)

Note:


For the recommended tightening torques, please see the technical information from the manufacturer.

Notice

Wedge lock washers made of surface-hardened stainless steel 1.4404 are not suitable for use in corrosive environments. For corresponding applications, we recommend the use of 254SMO (1.4547) stainless steel wedge lock washers.
