Torsional shear bolts of steel structure

             Torsional shear Bolts of steel structure/Torsional shear bolts of high strength steel structure, Class 10.9

Steel structure torsional shear bolt Steel structure torsional shear bolt is a kind of High Strength Bolt, but also a kind of standard parts. Steel structure point. Steel structure bolts are divided into torsional shear high-strength bolts and large hexagonal high-strength bolts, large hexagonal high-strength bolts belong to the high strength level of ordinary screws, and torsional shear high-strength bolts are the improvement of large hexagonal high-strength bolts, in order to better construction. The large hexagon structural bolt consists of one bolt, one nut, and two washers.

Torsional shear steel structure bolt consists of a bolt, a nut and a Washer. In general steel structure, steel structure bolts are required to be above grade 8.8, as well as grade 10.9 and grade 12.9, all of which are high strength steel structure bolts. Sometimes the bolts on steel structure do not need electroplating. The length of torsional shear high strength bolt is the length from the supporting surface of the Screw head to the incision of the screw tail. The torsional shear bolt has a plum head at the tail of the screw. The nut is tightened with a special wrench during construction, and the torque when the plum head is broken is the standard torque. They all belong to the friction type high strength suppository, can be replaced

However, torsional shear type high strength bolt does not need to calculate torque, torque is easy to ensure, can avoid the occurrence of calculation errors or ordinary wrench instead of torque wrench so as to ensure the final twist torque phenomenon. The size of the hexagonal head of the steel structure big hexagon bolt connecting pair and the general hexagonal head of the hexagonal head of the steel structure big hexagon bolt connecting pair is greater than that of the ordinary hexagon Head Bolt products, so the steel structure big hexagon bolt connecting pair can also be called the steel structure big hexagon bolt connecting pair. Steel structure big hexagon bolt connecting pair is mainly used for industrial and civil construction, railway bridge, highway bridge, pipeline bridge, tower mast structure, boiler frame, boiler steel structure, large span industrial plant, high-rise civil building, all kinds of tower, light steel structure, lifting machinery and other steel structure connecting construction
