What is the difference between an electric wrench and a pneumatic wrench? 


An electric wrench is a wrench powered by a power source or a battery. It is a tool for tightening bolts; a pneumatic wrench is a tool that provides high torque output with minimal consumption. Next, let's take a look at the difference between various types of wrenches.  


Electric wrench: It is a wrench powered by a power supply or a battery. It is a tool for tightening bolts. Mainly used in the steel structure installation industry, special installation of high-strength steel structure bolts, high-strength bolts are used to connect steel structure joints, usually in the form of bolts.   


Pneumatic wrench: also known as the combination of ratchet wrench and power tool, mainly a tool that provides high torque output with minimum consumption. It accelerates the rotation of an object with a certain mass through a continuous power source, and then instantly hits the output shaft, so that it can obtain a relatively large torque output. Compressed air is the most common source of power, but there are also electric or hydraulic ones. Widely used in many industries, such as car repair, heavy equipment repair, product assembly (commonly known as 'pulse tool' and designed for precise torque output), major construction projects, installation of steel wire screw sleeves, and high torque in any other place Output   


Impact electric wrench: It is mainly for the initial tightening of the bolt. Its use is very simple, just align the bolt and pull the power switch.   

Electric torsion shear wrench: It is mainly for tightening the torsion shear type high strength bolt. Its use is to align the bolt and pull the power switch until the torx head of the torsion shear type high strength bolt is interrupted.   


Electric fixed torque wrench: It can be used for initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts.   


Electric corner wrench: It is also a kind of fixed torque wrench. Its use is to adjust the degree of rotation first, and then tighten the bolt.   Electric angle wrench: It is an electric wrench specially used to fasten the bolts at the angle part of the steel frame. Its use is the same as the principle of the electric torsion shear wrench.
