1、大六角高强螺栓可以替代扭剪型，反过来扭剪螺栓不能代替大六角。
1. The large hexagon high strength bolt can completely replace the torsional shear type, on the contrary, the torsional shear bolt can not completely replace the large hexagon.
2、螺栓：机械零件，配用螺母的圆柱形带螺纹的紧固件。由头部和螺杆（带有外螺纹的圆柱体）两部分组成的一类紧固件，需与螺母配合，用于紧固连接两个带有通孔的零件。 这种连接形式称螺栓连接。如把螺母从螺栓上旋下，又可以使这两个零件分开，故螺栓连接是属于可拆卸连接。
2. Bolt: mechanical part, cylindrical threaded fastener with nut. A kind of fastener composed of head and screw (cylinder with external thread), which is used to connect two parts with through-hole by matching with nut. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
