市场电扳手琳琅满目，若是硬要一款，或许有失偏颇，其实挑选一款高质量的合适的电扳手只需把握几种要素。
There are a wide range of electric wrenches in the market. If you insist on recommending a brand, it may be biased. In fact, you only need to grasp several elements to select a high-quality and appropriate electric wrench.
一、看扳手参数；扳手的参数是需要关注的首要节点，直接决定了扳手的工作性能。
1、 See the wrench parameters; The parameters of the wrench are the primary node that needs attention, which directly determines the working performance of the wrench.
二、看扳手材料选购电动扳手时，另一个要关注的要点便是机体材料的选用，市面上常见电动扳手的材料一般采用橡胶与铁制品结合，弊端在于容易生锈或老化，若能选择高硬度、耐腐蚀、耐磨的材质，显然能增加工作效率，提高使用寿命和延展性。
2、 When looking at wrench materials, another key point to pay attention to when purchasing electric wrenches is the selection of body materials. The materials of common electric wrenches on the market generally use the combination of rubber and iron products. The disadvantage is that they are easy to rust or aging. If you can choose materials with high hardness, corrosion resistance and wear resistance, it can obviously increase work efficiency and improve service life and ductility.
三、看与售后不管是选购电动扳手，还是其他商品，和售后也是需要关注的重要要点。选购具有的扳手，不仅是它质量的保证，也意味着在未来的使用过程中，一旦电动扳手出现异常，也能轻松问题。
3、 Look at the brand and after-sales. Whether it is to buy electric wrenches or other goods, the brand and after-sales are also important points to pay attention to. Choosing a brand wrench is not only the guarantee of its quality, but also means that in the future, once the electric wrench is abnormal, it can easily solve the problem.
终紧扭剪型高强螺栓需要用扭剪型高强螺栓扳手，因为扭剪型高强螺栓的终紧一定要把它的梅花头打断，只有扭剪型高强螺栓扳手才能。 高强螺栓的紧固需要先初紧再终紧，扭剪型高强螺栓的初紧可以选择冲击电动扳手、定扭矩电动扳手或扭剪型电动初紧扳手，并且一般达到终紧扭矩的50-60%就可以了。
The final tightening of torsional shear high-strength bolt requires torsional shear high-strength bolt wrench, because the final tightening of torsional shear high-strength bolt must break its plum blossom head. Only torsional shear high-strength bolt wrench can. The tightening of high-strength bolts requires initial tightening before final tightening. The initial tightening of torsional shear high-strength bolts can choose impact electric wrench, constant torque electric wrench or torsional shear electric initial tightening wrench, and generally it can reach 50-60% of the final tightening torque.
