A square head bolt is a mechanical component typically composed of a screw and a nut. Its head is square and easy to rotate with a wrench. The materials of square head bolts are generally carbon steel, alloy steel, stainless steel, copper, and aluminum. Due to its simple structure, reliability, and wide applicability, it is widely used in various mechanical equipment.
The purpose of square head bolts
Square head bolts are widely used in mechanical equipment, automobiles, railways, bridges, rail transit, construction industry, shipbuilding, aerospace, power electronics and other fields. Mainly used to fix two or more parts, it can also be used to adjust tightness and prevent loosening. Compared to other connectors, the advantage of square head bolts is that they have a greater load-bearing capacity, making the machine equipment more secure and reliable.
Characteristics of square head bolts
1. Simple structure: The square head bolt has a simple structure and is easy to manufacture and assemble.
2. Firm and reliable: The head of the square head bolt is square, with good fixation performance and long service life.
3. Easy installation: The head design of the square head bolt can be rotated using a wrench, without the need for specialized tools.
4. Wide applicability: Square head bolts can be applied to various mechanical equipment and have a very wide range of applications.
5. Easy maintenance: Square head bolts are easy to disassemble and maintenance is simpler.
In short, square head bolts are a widely used mechanical component in mechanical equipment, characterized by simple structure, firmness and reliability, and convenient installation. It not only has good fixation performance, but also has a long service life and is easy to repair and repair.
Square head bolts are divided into 4.8 grade bolts, 8.8 grade bolts, 10.9 grade bolts, and 12.9 grade bolts according to their high-strength grade. They are divided into iron bolts and stainless steel bolts according to the material of the screw wire. Stainless steel bolts include stainless steel SUS304 bolts, stainless steel SUS201 bolts, and stainless steel SUS316 bolts.
