使用方法是在扳bai手上調整到你需要du的扭矩值，用扳手鎖螺栓的時候當?shù)絲hi達扭矩值就會發(fā)出咔嗒聲。這時要dao馬上松開螺栓，以免過扭。
The way to use it is to adjust the torque value of DU on the wrench Bai. When the bolt is locked with a wrench, when the torque value reaches Zhi, it will make a click. At this time, Dao should loosen the bolt immediately to avoid over twisting.
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。
Torque wrench is used to fasten bolts. High strength bolts can be divided into torsion shear type and large hexagon type. There are four kinds of national standard torsional shear high-strength bolts: M16, M20, M22 and M24, and now there are non-national standard M27 and M30; national standard large hexagon high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts should be first and then final tightening, and each step needs to have strict torque requirements.
力矩扳手又叫扭矩扳手、扭力扳手、扭矩可調扳手，是扳手的一種。按動力源可分為：電動力矩扳手、氣動力矩扳手、液壓力矩扳手及手動力矩扳手；手動力矩扳手可分為：預置式、定值式、表盤式、數(shù)顯式、打滑式、折彎式、以及公斤扳手。
Torque wrench, also known as torque wrench, torque wrench, torque adjustable wrench, is a kind of wrench. According to the power source, it can be divided into electric torque wrench, pneumatic torque wrench, hydraulic torque wrench and manual torque wrench; the manual torque wrench can be divided into preset type, fixed value type, dial type, digital display type, sliding type, bending type and kg wrench.
