力矩扳手又叫扭矩扳手、扭力扳手、扭矩可調(diào)扳手，扭矩扳手是扳手的一種，一般分為兩類：電動力矩扳手和手動力矩扳手。
Torque wrench is also called torque wrench, torque wrench, torque adjustable wrench. Torque wrench is a kind of wrench, generally divided into two categories: electric torque wrench and manual torque wrench.
力矩扳手主要特征就是：可以設定扭矩，并且扭矩可調(diào)。
The main feature of torque wrench is that the torque can be set and adjusted.
力矩扳手的應用：
Application of torque wrench:
力矩扳手就是緊固螺栓的，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，現(xiàn)在也有非國標的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。大六角高強螺栓的初緊和終緊都建議使用定扭矩扳手。
Torque wrench is used to fasten bolts. High strength bolts can be divided into two types: torsional shear type and large hexagon type. National standard torsional shear type high strength bolts are M16, M20, M22 and M24, and now there are two kinds of non-national standard M27 and M30. National standard large hexagon high strength bolts are M16, M20, M22, M24, M27 and M30. Generally, for the fastening of high-strength bolts, the initial tightening and then the final tightening are required, and strict torque requirements are required for each step. Constant torque wrench must be used for initial and final tightening of large hexagon high strength bolt.
