Common bolt is one of the common fasteners in steel structure engineering. Welding nail manufacturer: the welding nail belongs to a fastener with high strength and rigidity. The welding nail is the abbreviation of the cylindrical head welding nail for arc stud welding. The specification of the welding nail is the nominal diameter Ф 10～ Ф 25mm, the total length before welding is 40-300 mm. The welding nail has the identification mark of the manufacturer made by the convex characters on the top surface of the head. The welding nail is widely used. Steel structure bolt manufacturer steel structure bolt is a high-strength bolt and a standard part. The fastening performance is relatively good. It is used in steel structure and engineering to make the fastening effect. In general steel structure, the required steel structure bolts are all grade 8.8 or above, and there are grade 10.9 and 12.9. All of them are high-strength steel structure bolts. Sometimes, the bolts on the steel structure do not need plating, and it is OK to use the natural color. It is more suitable for the connection of the middle parts of the 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 connection of bolts. Common bolts commonly used in life include hexagon bolts, stud bolts and anchor bolts fixed on the ground.
1. Hexagon bolts are generally more suitable for steel structures to play a temporary and firm role in the installation process, or they simply accept some blocking forces caused by friction between steel plates and do not act on other important connectors. However, on the surface of some more important connectors, if thick bolts are used for connection, it should be ensured that appropriate supports capable of withstanding shear forces are added during this period.
2. Also known as stud bolts. The slab converges and does not fit with hexagon bolts in some places
3. 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 all visible, and they have made contributions that cannot be ignored in the construction process.
