Anti-loosening fasteners for thread-based connections have special properties to maintain the clamp force of the assembly, even under high vibrations. This is especially relevant for safety-critical applications where the loosening or loss of fasteners can create tremendous damage.

 

In our broad portfolio of trusted brands, we offer lock washers, locknuts and multifunctional screws with special properties to keep bolted connections from becoming loose. The following mechanisms are most common:

  • Securing through friction
  • Securing through mechanical locking
  • Securing through tension

Additional to these mechanical solutions, anti-loosening can also be achieved by special adhesives. The optimal anti-loosening solution strongly differs from application to application. We look forward to supporting you with your challenge!
