Elastic telescopic tensioner (positioning)

The elastic telescopic tensioner is suitable for through-hole connection applications. It is a reverse thrust nut type tensioner, which can be flexibly bent. Under constant load, the bottom and top of the tensioner can freely expand and expand, which helps to relieve the pressure concentration and increase the fatigue resistance of the bolt, thus prolonging the service life of the matching bolt. Since the elastic telescopic nut is a reverse thrust nut, it is usually used in the tensioner On the contrary, one side does not directly twist to achieve the advantages of preload: ensuring that the load is evenly distributed on the bolt / stud thread under load; increasing the elasticity of the connector; increasing the fatigue strength of the bolt / screw and extending its service life.
