Electric wrench is an electric tool for tightening and loosening bolts and nuts. It is a tool for fastening high strength bolts. It is used for the initial twist, final twist and initial twist of shear type high strength bolts for installation of large hexagonal head high strength bolts in steel structure bridges, factory buildings, chemical industry and power generation equipment, as well as the occasions where the torque or axial force of bolt fasteners is strictly required. The following is a small twist scissors wrench knitting to introduce the use of electric wrenches caution!
