TREP® is designed as an anti-loosening security system for all mechanical bolting connection, which consists of 3 or 4 interdependent smooth tapered spring washers with a metal insert. As a safety element, disc spring assemblies maintains constant tension and clamping force in the joint. Even though slight relaxation may occur, the elastic properties of TREP® ensures that the system can withstand loosening in high-stress applications where residual tension in the bolt is of vital importance, or in another words, completely secure and reliable fastening, no concern about the problem of vibration or loosening.

 

 

For soft surfaces such as aluminum, copper or brass, the special solution TREP plus® distributes the clamping force over a larger surface area without slipping.
