　　扭剪型电动扳手是用来紧固扭剪型高强度螺栓的，又称为梅花头螺栓。这种螺栓设计为固有的预拉力，以拧断螺栓的梅花头作为紧固螺栓，以达到预紧力的标准。
    扭剪型高强度螺栓的紧固必须分两次进行：**次为初拧，初拧紧固到螺栓标准轴力（即设计预拉力）的50%～80%，初紧的扭矩值不得少于终拧扭矩值的30%；*二次紧固为终拧，终拧时，扭剪型高强度螺栓应将梅花头拧掉，为使螺栓群中所有螺栓均匀受力，初拧、终拧都应按一定顺序进行。
    扭剪型电动扳手广泛用于电力建设、冶金建设、化工建设、桥梁建设、高层建筑等钢结构的安装紧固。
Electric shear wrench was used to fastened the TC bolts .Tension control bolts ,also called "twist-off"bolts ,these bolts have a splined extension that will disconnect when the bolts' tension reaches a predetermined value. So twist-off the splined extension means that it have reached to the bolts' pre-tension design.

High-strength bolts fastening is divided into two parts . For the first time early mistake, standard screw fastening bolts early access to axial force (pre-tension design)60%-80% of the initial value of torque twist the screw end torque value of not less than 30% .Second screw fastening to the end ,when the final twist torsion and shear type cards with high-strength bolts should first shake off  Plum .To enable all groups bolts by bolts uniform ,the early mistake seekers have eventually make certain order .

Electric shear wrench is perfectly used in the Power Plant Construction ,Metallurgical Construction,Chemcal industry construction,bridge construction ,Steel frame buildings. Which is professional for metal fastening work .
