Wire thread insert, other names we called threaded bushing; screw Insert, wire thread insert is a fastener element that is inserted into an object to add a threaded hole.
It is made of high strength, precision, corrosion resistant and diamond wire.
Advantages for screw threaded insert:
1). it could enhance the connection strength and abrasion resistant, especially in AL, MG, Cast Iron and other low strength materials.
2).improve thread's stress state and to be spring connection, remove the errors of pitch and thread angle, protect the thread
avoiding to be broken, and extend working time.
3). prevents the thread rusting, trip with perfect corrosion, high heat and abrasion resistant in many kinds of environments,repair the internal thread.
Applications:
Widely used in large automobile manufacturing, metallurgy, electric power, machinery,
chemical fiber, chemical industry.

Installation process:
Drilling→Tapping→Installing→Breaking off tang
Tools:
1.Drill: used for drilling the base holes
2. taps: used for the processing special internal thread of the base holes.
3.Installation tools: put sets into the threaded hole.
4.Break-off tools: break off the tang of thread insert.
5.Extraction tools: used for removing the damaged thread insert from the threaded hole.
