电动扳手主要应用于钢结构安装行业，专门安装钢结构高强螺栓，高强度螺栓是用来连接钢结构接点的，通常是用螺栓群的方式出现。
Electric wrenches are mainly used in the steel structure installation industry to install high-strength bolts of steel structures. High strength bolts are used to connect steel structure joints, usually in the form of bolt groups.
高强螺栓可分为扭剪型和大六角型两种，国标扭剪型高强螺栓为M16、M20、M22、M24四种，非国标的M27、M30两种；国标大六角高强螺栓为M16、M20、M22、M24、M27、M30等几种。一般的对于高强螺栓的紧固都要先初紧再终紧，而且每步都需要有严格的扭矩要求。
High strength bolts can be divided into torsional shear type and large hexagon type. National standard torsional shear type high strength bolts are M16, M20, M22 and M24, and non-national standard M27 and M30; The national standard large hexagon high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts should be carried out initially and then finally, and strict torque requirements are required for each step.
大六角高强螺栓的初紧和终紧都需要使用定扭矩扳手.故各种电动扳手就是为各种紧固需要而来的。
Constant torque wrench shall be used for initial and final tightening of large hexagon high-strength bolts Therefore, various electric wrenches are provided for various fastening needs.
