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.
