Application and installation features of steel structure bolts

The full name of steel structure bolt in production is steel structure bolt connection pair, generally not referred to as high-strength bolt.

       Steel structural bolts are mainly used for the construction of industrial and civil buildings, railway bridges, highway bridges, pipeline bridges, tower and mast structures, boiler frames, boiler steel structures, large-span industrial plants, high-rise civil buildings, various towers, light steel structures, hoisting machinery and other steel structure connecting buildings.

       According to the installation characteristics, steel structure bolts are divided into large hexagon head bolts and torsional shear bolts.

       When the strength torsional shear type bolt connection pair is assembled, the side of the nut with the round table shall face the side with chamfer of the washer; The main advantage is that the construction of large hexagon bolt is simple, and the construction space required is small. The use of electric wrench can directly screw off the end of the box head, which is safe, simple and fast, and it is very convenient to check the construction quality, but the production cost of the strength torsional shear type bolt connection pair is higher than that of the hexagon bolt.
