How to choose an electric wrench?
The torsional shear type is specially used for twisting and shearing type bolts. The electric wrench is selected according to the specifications of the bolt. The fixed torque is mainly used in the occasions where the torque is required, and the electric spanner is selected according to the torque magnitude.
For the main purpose, the torque, torsion shear type and impact type are generally determined.
Impact type electric wrench is cheap and efficient, but the torque accuracy is poor. The electric spanner is mainly selected according to the bolt specification.
