Nord-Lock ontwierp de originele wigborgtechnologie die boutverbindingen fixeert zelfs wanneer ze blootstaan aan extreme trilling en dynamische belastingen. Door de wig die onder boutkop en moer ontstaat, kunnen onze producten onmogelijk zomaar losdraaien.

Nord-Lock Combiboutringen

Nord-Lock combiboutringen zijn speciaal ontworpen om permanent aan een bout (SEMS) te worden bevestigd, als een extra veiligheidslaag bij diverse toepassingen.

Het standaardassortiment van Nord-Lock combiboutringen bestaat uit NL5 - NL12 van staal. Complete combibouten, inclusief Nord-Lock combiboutringen, kunnen worden aangeboden in samenwerking met een lokale boutproducent. 


Proven wedge-locking technology

The washers are developed based on our proven wedge-locking technology but have a reduced inner diameter preventing them from falling off the bolt after the thread is added.


  • Ensures faster product assembly, thanks to pre-assembled parts
  • Decreases failures related to human error, incorrect mounting or forgetting to put on the washers
  • Facilitates product assembly of very small sizes
  • Allows maintenance and repairs in areas that are difficult to reach or of limited access
  • Facilitates inventory and logistical savings due to reduced number of items
  • Faster and easier disassembly, as loose washers can be difficult to remove, especially from counter bore holes

Testing & Certification

Nord-Lock combi bolt washers have been rigorously tested and approved by the Nord-Lock engineering team. The standard range of Nord-Lock combi bolt washers are ready to be shipped to you for testing/evaluation. Combi bolt washers in other sizes, metric and UNC, with standard diameter or enlarged outer diameter (sp) as well as washers in other materials are offered upon request.
