Product Description:
Ordinary steel wire is a new type of a screw fasteners, the other is a locking type, my company at the time of production is the accuracy of the diamond section of stainless steel wire precision machining, molding spring shape can be achieved after the effect of internal and external thread concentric body.
For locking type steel wire, a screw is on the basis of the normal increase once or several times clamp ring.When using steel wire embedding a screw inside of aluminum, magnesium, iron and plays a protective role in the process of extrusion formation of M, MJ threads, thread and disperse stress to protect matrix, and greatly prolong the service life of the matrix.
In addition, steel wire spiral sets also have the function that repair, does not need to increase the screw size, can quickly and effectively to repair to the original state, and does not cause the whole matrix of scrapped, rapid economy.
At the time of installation, installation personnel must watch carefully because if there is a deviation, then can only about 70% of the load bearing on thread mouth end of thread.This will lead to most stress is concentrated to be preloaded force premature loss together.The result will tighten loose caused the failure directly.
