Differences between bolts

Ordinary bolt is one of the common fasteners in steel structure engineering. The stud manufacturer's stud is a kind of fastener with high strength and rigidity. The stud is the abbreviation of cheese head studies for arc stud welding. The specification of the stud is nominal diameter of Ф 10 ~ Ф 25mm, and the total length before welding is 40 ~ 300 mm. The welding pin has the head top surface, and the manufacturer's identification mark is made by convex characters, so the welding pin is widely used. Steel structure bolt manufacturer steel structure bolt is a kind of high strength bolt, which is also a kind of standard parts. Good fastening performance, used in steel structure, engineering, so that the tightening effect. General steel structure, the requirements of steel structure bolts are 8.8 grade or above, there are 10.9 grade, 12.9 grade, all of them are high strength steel structure bolts, sometimes the bolts on steel structure do not need electroplating, use the natural color is OK. It is more suitable for the connection of various parts in the middle of steel structure and plays a more solid role. It can also be said that some parts are scattered and become a complete individual through the bolt connection. The common bolts commonly used in life are hexagon bolt, stud bolt and anchor bolt fixed on the ground. Next, let's ask the person in charge of the new national standard bolt manufacturer to explain their scope of use
1. Hexagon bolts are generally more suitable for steel structures to play a temporary and firm role during installation, or they simply accept some blocking forces caused by friction between steel plates and steel plates and do not act on other important connections, but on the surface of some more important connections, if thick bolts are used, it should be ensured that the addition can withstand shear during this period Proper support for force.

2, also known as stud bolt. In the slab convergence, some places do not fit the hexagon bolt.
3. The foundation bolts can be divided into several types according to their functions. Each type is responsible for different areas, which can perform its duties well. It can be said that as long as it is a construction project, they are visible, and provide a contribution that can not be ignored in the construction process.
