Application and installation characteristics of

steel structural bolts

Steel structure bolts are commonly referred to as steel structure bolt connection pairs in production, and are not generally referred to as high-strength bolts.

Steel structure bolts are mainly used in 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 structural join buildings.

Steel structural bolts are divided into large hexagonal head bolts and torsional shear type bolts based on installation characteristics.

When assembling the strength torsion shear type bolt connection pair, the side of the nut with a circular table should face the chamfered side of the washer; The main advantage is that the construction of large hexagonal bolts is simple, and the required construction space is small. Using an electric wrench to directly unscrew the end of the plum blossom head is safe, simple, and fast, and the inspection of construction quality is very convenient. However, the production cost of high-strength torsion shear bolt connection pairs is higher for hexagonal bolts.
