Combi Bolt Washers

Nord-Lock created the original wedge-locking technology that secures bolted joints, even when exposed to severe vibration and dynamic loads. It is impossible for our products to loosen unintentionally due to the wedge created underneath the bolt head and nut.

Combi bolt washers

Nord-Lock combi bolt washers are specifically designed to be permanently attached to a bolt (SEMS), providing an additional layer of security to applications.

The standard range of Nord-Lock combi bolt washers consists of NL5 - NL12 in steel material. Complete combi bolts, including Nord-Lock combi bolt washers, are offered in co-operation with a local bolt manufacturer. 

 

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.

Advantages

  • 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.
