    Thread insert is a new internal thread fastener, which is made of diamoond-shaped stainless steel wire with high precision,high strength and corrosion resistance, and it looks like spring, when installing it into special thread hole,the hole is still the standard one, and it can obviously improve connection strength and wear resistance when used with a bolt, on magnesium,cast iron,plastic and other soft materials in particular.Hard as the threading insert is,there are difficulties in screwing into bottom hole, now let's start to acquire some technical points.

a.When installing coil with simple installation tool, the insert cannot get precompression that may cause over torque: change a socket spanner.

b.Installing self locking bushing with simple installation tool: change a matched installation spanner.

c.The guidance thread of socket spanner is wearing out so much that causes unproper precompression: using a special matched plug gauge to check guidance thread of spanner, if the non-go gause doesn't work,change a new socket spanner.

d.The bottom hole is not clear and clean: clear it up to make the installation easy

e.The drill is too small: change a proper one.

f.The tap is wearing out: change a new one.

g.The installation handle is far away from thr center: correct it with a pilers or contact with factory and change it.
