Original Nord-Lock wedge lock technology with CE marking and laser marking. For effective thread locking on laterally loaded, vibrating screw connections and screw connections subject to oscillations to prevent self-turning.

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)

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)
