Brief introduction
An electric wrench is a power-powered or battery-powered wrench and is a tool for tightening bolts. Mainly divided into impact wrenches, torsion shear wrenches, fixed torque wrenches, corner wrenches, corner wrenches, hydraulic wrenches, torque wrenches, and cordless electric wrenches.

Electric wrenches are mainly used in the steel structure installation industry, specially installed steel structure high-strength bolts, high-strength bolts are used to connect steel structure contacts, usually in the way of bolt groups. High-strength bolts can be divided into two types: torsion-shear type and large hexagonal type, the national standard torsion-shear type high-strength bolt is M16, M20, M22, M24, and the non-national standard M27 and M30; The national standard large hexagonal high-strength bolts are M16, M20, M22, M24, M27, M30 and so on. Generally, the tightening of high-strength bolts must be first tightened and then finally tightened, and each step needs to have strict torque requirements. Both the initial and final tightening of the large hexagonal high-strength bolt must use a constant torque wrench. Therefore, all kinds of electric wrenches are for various fastening needs.
Use effects
Impact electric wrenches are mainly used to tighten bolts, and its use is very simple, that is, align with the bolts to trigger the power switch. The electric torsion shear wrench is mainly used to finally tighten the torsion-shear high-strength bolt, and its use is to align the bolt to trigger the power switch until the plum head of the torsion-shear high-strength bolt is broken. The electric fixed torque wrench can be both initially and finally tightened, and its use is to adjust the torque first and then tighten the bolt. Electric corner wrenches are mainly a kind of fixed torque wrench, which is used to adjust the degree of rotation first, and then tighten the bolt. The electric angle wrench is an electric wrench that specializes in tightening the bolts at the angle of the steel frame, and its use is the same as the electric torsion shear wrench.
performance
As the name suggests, the electric torsion shear wrench is an essential tool for torsion and shear torque head bolt tightening operations, helping you to install and remove screws and nuts, and at the same time control the tightening torque more accurately. Using the fixed torque of the bolt, when the wrench reaches a certain torque, the plum head part of the bolt can be cut, and its torque accuracy and axial tension are guaranteed by the fixed torque V-shaped cut of the bolt. The torque torque of disassembly and assembly is large, which is safer and more reliable than manual assembly. Convenient, beautiful, practical, easy to carry with the car. It is widely used in the construction of steel structure bridges, workshops, power generation equipment and other facilities.
The characteristics of the electric wrench: (1) long service life (2) good heat dissipation of handle and chassis materials (3) high power (4) strong impact resistance (5) the most cost-effective for hand use
Electric torsion shear wrench is a tool for final tightening torsion shear type high-strength bolts, generally there are electric torsion shear wrenches and manual torsion shear wrenches, of which electric torsion shear wrenches are more common.
Application of torsion shear wrench: The initial tightening of torsion-shear high-strength bolts can use impact electric wrenches or fixed-torque wrenches, and the final tightening must use torsion-shear wrenches, so torsion-shear wrenches are specially designed to finalize torsion-shear high-strength bolts.
The use of torsion shear wrench: The torsion shear wrench is mainly used to finally tighten the torsion shear type high-strength bolt, and its purpose is to break the plum head of the torsional shear type high-strength bolt. When working, align the wrench head with the bolt head, pull the switch to start working, after a few seconds, the bolt plum head will be twisted off, and then pull out the wrench to pull the trigger to eject the plum head, that is, end the work.
Features of torsion shear wrench: easy to operate, time-saving and labor-saving, safe and convenient.
Folding advantage
1. Easy to operate.
Second, save time and effort.
Third, the price is high.
