Locking Type Wire Thread Insert DIN8140 ST8*1.25

There are 1 to 2 turns of pentagonal or hexagonal shape in the middle of the locking type wire screw sleeve. When the bolt is screwed halfway into the threaded hole, the head of the bolt hits the locking ring. Other conventional locking devices have superior locking performance and higher strength, and can be disassembled repeatedly.

The locking type is to add one or several turns of the locking ring on the basis of the ordinary type, which can tighten the assembly screws and prevent loosening. Wire thread inserts are embedded in threaded holes of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass steel, plastics, etc., and can form high-precision internal threads that meet international standards. They have high connection strength, earthquake resistance, impact resistance and wear resistance. Function, and can disperse the stress to protect the thread of the base body, greatly extending the service life of the base body

When the screw is screwed into the screw hole of the locking type steel wire thread sleeve, it is loose before entering the polygonal locking ring. When the screw enters the polygonal locking ring, the polygon needs to be opened to deform the locking edge. At this time, the screw in needs to overcome the friction force of the locking edge on the screw. After the screw is tightened, the friction force can prevent the screw from loosening by itself, thus replacing other locking methods.
