The common thread insert
It is composed of the multi-turn helix of rhombic and be
capable of enhancing the screw connecting strength。 It is divided
into two categories, with gutter of rupture and without gutter of
rupture. The former is used for the through hole or the blind hole
and the latter is used for the blind hole only.
the locking thread insert
It is composed of the multi-turn helix of rhombic and has more than one polygon locking ring。 when the nut is screwed into the locking devices it is locking ring can lock the nut after pressure to prevent the screen joint loosening。
The special tap
Material: the high-speed steel (6542 9341).
It is used to work the thread insert’ s bottom hole which is used mechanically and manually .it is divided into three categories . the seraigh channel ,the spiral scroll and the squeezing tap.

The manual wrench
Material:≤M8LY12 ≥M10 45#steel
It is used for the installment of the thread insert 。It is the basic principle that the thread insert is guided 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。
The electric wrench
The using range :M3~M12
It is used in the assemblage of the multitudinous thread insert or used in the assembling the production。
The tail of break-off tool
It is used in breaking off the thread insert tail of the through hole, the break-off tool is aligned to the tail and breaks it off with a 200g hammer punching to form it into the throng hole。
Material:the high-speed steel
Enable users to extract a thread insert fitted with defect. Thanks to it is triangular shape. the extractor can be locked into the thread insert, by rotating the tool while keeping a vertical thrust, the thread insert can be unscrewed.
It enables users to check the conformity of the tapping before insertion of thread inserts for the work piece for having high accuracy.
The self-locking nut
It makes the nut impossible to unscrew when the machine is vibrating, after the locking thread insert is stetted into the nut. It is capable of removing and using time after time
Repair tool kit
Repair kits provide all necessary tools thread tapping or to quickly and economically repair them。
