There are many names for hex bolts. Everyone's name may be different. Some people call them screws, some are called bolts, some are called standard parts, and some people call them fasteners. Although there are so many names, the meanings are the same, they are bolts.

Bolt bolts are a general term for fasteners. The principle of the bolt is to use the physics and mathematical principles of the circular rotation of the object and the frictional force to gradually tighten the tool of the object.

Bolts are indispensable in daily life and industrial production. Shaped hexagon bolts and bolts are also called industrial rice. It can be seen that the use of bolts is extensive. The scope of application of bolts is: electronic products, mechanical products, digital products, electrical equipment, Shanxi Hex bolts, electromechanical machinery products. Bolts are also useful for ships, vehicles, non-standard hex bolts, hydraulic engineering, and even chemical experiments. Anyway, many places use bolts. Special precision bolts used in digital products. Miniature bolts for DVDs, cameras, glasses, clocks, electronics, etc.; general bolts for televisions, electrical products, musical instruments, furniture, etc.; for engineering, construction, bridges, large bolts and nuts; traffic appliances, airplanes, trams, cars Then use the size bolts. Bolts have an important task in the industry, the national standard hex bolts, as long as there is industry on the earth, the function of bolts is always important.
High-strength bolts are made of high-strength steel or bolts that require a large pre-tightening force, which can be called high-strength bolts. High-strength bolts are often used for the connection of bridges, rails, high-pressure and ultra-high pressure equipment. The breakage of such bolts is mostly brittle fracture. High-strength bolts used on ultra-high pressure equipment require large pre-stresses to ensure the seal of the container. High-strength bolts are generally classified into 8.8 grades. 10.9 grades 12.9 grades vary in hardness and yield depending on the grade.
