扭剪扳手的套筒，一種型號(hào)只能擰一種螺栓，比如27#套筒只能擰m16一種螺栓，不管螺栓長(zhǎng)度多長(zhǎng)，都可以擰，但是不能擰其它型號(hào)的螺栓
The socket of a torsion wrench can only be used to tighten one type of bolt per model, for example, the 27 # socket can only tighten one type of bolt per m16. Regardless of the length of the bolt, it can be tightened, but other types of bolts cannot be tightened
所有每臺(tái)扳手都可以換不同型號(hào)的套筒，用來(lái)擰不同型號(hào)的螺栓
All wrenches can be replaced with different types of sockets to tighten different types of bolts
扭剪扳手專(zhuān)用于扭剪螺栓的使用，一般鋼結(jié)構(gòu)工程中比較常用。
The shear wrench is specially used for shear bolts, which is commonly used in general steel Structural engineering.
鋼結(jié)構(gòu)工程中有大六角螺栓也有扭剪螺栓，大六角螺栓只能用定扭矩扳手，不能用扭剪扳手，而扭剪螺栓也只能用扭剪扳手來(lái)擰，不可以使用定扭矩扳手，兩種螺栓造型不同，使用不同的扳手，所以一定要確定螺栓是什么類(lèi)型的，根據(jù)螺栓來(lái)挑選適合的扳手。
There are both large hexagon bolts and shear bolts in the steel Structural engineering. Large hexagon bolts can only be tightened with a fixed torque wrench, not a shear wrench, while shear bolts can only be tightened with a shear wrench, not a fixed torque wrench. The two types of bolts have different shapes and use different wrenches, so it is necessary to determine what type of bolt is and select the appropriate wrench according to the bolt.
