What is the purpose of the sems screw?

We don’t know much about the sems screw. That’s because we don’t know the purpose of the sems screw. Today, the Shi Shi Tong screw factory says the purpose of the sems screw, please look down.

Usually, high-strength large hex head bolt sems screws for steel structures are mainly used for railway and highway bridges, boiler steel structures, industrial plants, high-rise civil buildings, tower structures, lifting appliances and their steel structures. High-strength bolt sems screw. It is characterized by a bolt, which is also called a twelve-horned body at the end of the bolt. When installing, a special electric wrench must be used. There are two sleeve heads on the top and bottom, one on the hexagonal body of the nut and the other on the tenth angle of the hexagonal screw. This type of screw has a higher strength requirement. When tightening, apply a clockwise force to the nut and apply an equal counterclockwise force to the bolt’s dodecahedron so that the end of the hexagonal screw and the dodecagon are connected to the neck to be twisted and sheared to the neck. So far, the installation is over. This torsion-cut type high-strength hex screw is a one-size type screw that cannot be removed after installation.
