扭矩扳手扭矩扳手的主要特点是扭矩扳手可以设定扭矩，扭矩可以调节。扭矩扳手的应用:扭矩扳手用于紧固螺栓，高强度螺栓可分为扭剪型和大六角型两种。国标扭剪型高强度螺栓有M16、M20、M22、M24，现在还有M27、M30两种非国标；国标大六角高强度螺栓有M16、M20、M22、M24、M27、M30等。
Torque wrench the main feature of torque wrench is that the torque can be set and adjusted. Application of torque wrench: torque wrench is used to fasten bolts. High strength bolts can be divided into two types: torsional shear type and large hexagon type. There are M16, M20, M22 and M24 high strength bolts in the national standard, and there are M27 and M30 non national standards; there are M16, M20, M22, M24, M27 and M30 large hexagon high strength bolts in the national standard.
高强度螺栓的紧固一般要先拧紧再拧紧，每一步都要求严格的扭矩要求。大型六角高强度螺栓的初拧和终拧必须使用恒扭矩扳手。
High strength bolts are usually tightened first and then finally, and strict torque requirements are required at each step. Constant torque wrench must be used for initial and final tightening of large hexagon high strength bolts.
2扭矩扳手的使用编辑扭矩扳手可以先拧紧，拧紧。它的用途是先调节扭矩，再拧紧螺栓。本发明具有操作方便、省时省力、扭矩可调的特点。
2. Use of torque wrench the torque wrench can be tightened first and finally. Its purpose is to adjust the torque before tightening the bolts. The invention has the characteristics of convenient operation, time-saving and labor-saving, and adjustable torque.
