firstly to force the outside diameter shrinkage to pack it into the bottom hole smoothly. The efficiently is enhanced and the scrap rate is reduced through using the wrench
Helicoil is a new internal thread of fastener. It is made of high strength, precision,corrosion resistant
and diamond wire. The hfelicoil looks like spring, when it is assembled in matrix thread ,its internal
and diamond wire. The hfelicoil looks like spring, when it is assembled in matrix thread ,its internal
surface to be the standard thread . If helicoil is assembled with Screw, it could enhance the connection strength and abrasion resistant, especially in AL, Mg, Cast Iron and other low strength materials.
