Now many friends do not understand why the thickened nut should be so much thicker, and what use can the thickened nut be? What is the role of the thickened nut? When we use the thickened wood, in order to prevent the bolt from falling off from the fixer when we use the bolt, the manufacturer will thicken the nut according to the technical requirements, and the contact area of the nut bolt and thread is large, when using the thickened nut, it will ensure the stability of the bolt thread, which will prevent the bolt from falling off Slide off.
Thickened nut steel structure large hexagon bolt is a kind of high strength bolt, is also a kind of standard parts. Steel structure hexagonal bolt is mainly used in steel structure engineering, used to connect the connection point of steel structure steel plate. Steel structure bolts are divided into torsional 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 high-strength bolts are improved types of large hexagonal high-strength bolts, in order to better construction. The large hexagonal steel structural bolt consists of a bolt, a nut, and two washers. The shear steel structural bolt consists of a bolt, a nut and a washer. Thickening nut classification: according to the standard number can be divided into GB55,GB56(extra thick nut), according to the different material can be divided into high strength thickening nut and ordinary thickening nut, according to the surface treatment can be divided into electric galvanized thickening nut, hot dip galvanized thickening nut, dacromet thickening nut. The thickened nut (the thickened nut), like the ordinary nut, is used with the bolt, the difference is that the thickened nut has a larger thread than the ordinary nut, and the contact area with the bolt is larger, and it can withstand greater tension and lateral pressure than the ordinary nut. Therefore, it is commonly used in rail transit, large bridge construction, and large mechanical equipment. How to use the special table that wants the thickened nut to be fixed firmly? In fact, no thicker thickening nut has no locking effect, unless there is a nut, or a locking nut, if not, you can add a spring pad, and then brush with paint, you can play the role of thickening nut locking.
