Securing and anti-loosening elements have special properties to prevent the failure of thread-based connections. Through different mechanisms, they maintain the clamp force of the assembly, even under high vibrations. This is crucial especially for safety-critical applications where the loosening or loss of fasteners can create tremendous damage. 

Types of Securing and Anti-Loosening Fasteners 

There are different types of self-locking fasteners, including lock washers, locknuts, and multifunctional screws with special properties to keep bolted connections from coming loose. The following operating mechanisms are most common: 

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

In addition to these mechanical solutions, anti-loosening can also be achieved by special adhesives.

The optimal anti-loosening solution can differ greatly, depending on the application. We support you in finding the right choice for your specific challenge!
