Electric torsion shear wrench is a tool for final tightening of torsion shear type high-strength bolts. Generally there are electric torsion shear wrenches and manual torsion shear wrenches, among which electric torsion shear wrenches are more common Ratchet Wrenches.

Application of torsion shear wrenches: The initial tightening of torsion shear type high-strength bolts can use impact electric wrench or fixed torque wrench, and the final tightening must use torsion shear wrenches, so torsion shear wrenches are specially designed for final tightening of torsion shear type high-strength bolts.

 

The use of torsion shear wrench: The torsion shear wrench is mainly used for final tightening of torsion shear type high-strength bolts, and its purpose is to interrupt the plum head of torsion shear type high-strength bolts. When working, align the head of the wrench with the head of the bolt and pull the switch to start working. After a few seconds, the bolt head will be twisted. Then pull out the wrench and pull the trigger to eject the head, which means the end of the work.

 

Features of torsion shear wrenches: Convenient operation, time-saving, labor-saving, safe and convenient.

 

Application of electric wrenches Electric wrenches are mainly used in the steel structure installation industry, specializing in the installation of steel structure high-strength bolts. High-strength bolts are used to connect steel structure joints, usually in the form of bolt groups. High-strength bolts can be divided into torsion shear type and large hexagonal type.

 

The national standard torsion shear type high-strength bolts are M16, M20, M22, and M24, and the non-national standard M27 and M30 are two; the national standard large hexagonal high-strength bolts are M16 and M20 , M22, M24, M27, M30, etc. Generally, the fastening of high-strength bolts must be tightened first and then finally tightened, and each step requires strict torque requirements. Fixed torque wrenches must be used for the initial tightening and final tightening of large hexagonal high-strength bolts. Therefore, various electric wrenches are for various tightening needs.
