電動扳手主要應(yīng)用于鋼結(jié)構(gòu)安裝行業(yè)，專門安裝鋼結(jié)構(gòu)高強螺栓，高強度螺栓是用來連接鋼結(jié)構(gòu)接點的，通常是用螺栓群的方式出現(xiàn)。
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.
高強螺栓可分為扭剪型和大六角型兩種，國標扭剪型高強螺栓為M16、M20、M22、M24四種，非國標的M27、M30兩種；國標大六角高強螺栓為M16、M20、M22、M24、M27、M30等幾種。一般的對于高強螺栓的緊固都要先初緊再終緊，而且每步都需要有嚴格的扭矩要求。
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.
大六角高強螺栓的初緊和終緊都需要使用定扭矩扳手.故各種電動扳手就是為各種緊固需要而來的。
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.
