TREP®是一款适用于所有机械螺栓连接的防松安全系统，它由3到4个相互支撑，带金属嵌件的锥形弹簧垫圈组合而成。作为一款安全元件，碟形弹簧组件在连接中保持恒定的张力和夹紧力。尽管存在轻微松弛，但TREP®的弹性特征可以确保系统承受高应力环境中的松动，而螺栓中的残余张力值得关注，或者换句话说，这是一款绝对可靠的紧固方式，无需考虑振动或松动问题。

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.
In mechanical joints with material pairings and large jumps in stiffness (sheet metal joints made of aluminum, copper, or brass), the spring assembly can counteract a loss of preload force and shows greater resistance to loosening in the presence of applied vibrations than with individual clamping washers.
