U-bolts & Riding Pins: The head of a hot dip galvanized bolt is usually used where it needs to be joined. It is a non-standard part with a U-shaped shape, so it is also called a U-bolt. Hot dip galvanized bolts with threaded ends can be used in combination with nuts. It is mainly used to fix tubular or sheet objects. It is called a riding pin because of the way it holds things in place, just like riding a horse.
For steel structural connection bolts, unless otherwise specified, hot dip galvanized bolts are usually plain class C thick bolts. The rod of class A and B bolts is machined by the lathe, with smooth surface and accurate size. It has a material performance grade of 8.8 and is difficult to manufacture and install and expensive, so it is rarely used. ② Class C bolts are made of unprocessed round steel, the size is not precise enough, and the material performance grade is 4.6 or 4.8. The connection has large deformation, easy installation and low production cost.
Bolts are essential. Bolts are also known as industrial rice. As you can see, bolts are widely used. The application scope of bolt is: hot dip galvanized bolt, electronic products, mechanical products, digital products, electrical equipment, mechanical and electrical products. Bolts are also used in ships, vehicles, hydraulic engineering, and even chemical experiments.
