Hexagon socket head bolt is a commonly used screw-in machinery. It has the advantages of easy fastening and disassembly and non-slip angle. Hexagonal wrenches are generally 90 degrees, with one end long and one end short. When using short-side screws, holding the long side can save a lot of force and tighten the screws better. The manufacturing cost of the outer hexagon socket head bolt is much lower than that of the inner hexagon socket head bolt. Its advantage is that the screw head (the force position of the wrench) is thinner than the inner hexagon. In some places, the inner hexagon cannot be replaced. In addition, low-cost, low-power, and low-precision machines require fewer inner hexagon socket head bolts than outer hexagon socket head bolts.
The internal hexagon socket head bolt is also called a hexagon socket head bolt or a hexagon socket head bolt. It is a screw with a hexagon inner hole on the head, which can be tightened or loosened by inserting a hexagon wrench into the inner hole. The commonly used internal hexagon socket head bolt is a cylinder head screw, the head diameter of which is about 1.5 times the main diameter of the thread. Other types of heads include bottom cover screws for aesthetically pleasing surfaces and countersunk screws for tapered threaded holes. The counterbore design allows the screw head to rotate without being exposed to the surface of the fixed object, so it is often used in places where the surface is small and the use of traditional wrenches is inconvenient.
Hexagon socket head bolts are divided into hexagon socket head bolts and hexagon socket screws, which are usually used to fasten mechanical equipment. The hexagon socket head bolt is an externally threaded fastener with a hexagon head, which is designed to be turned with a wrench. The hexagon socket head bolt has a round head on the outside and a concave hexagon in the middle. The hexagon socket head bolt on the outside is a common hexagon socket head bolt. The inner hexagon socket head bolt looks like a ‘7’. It is cut into two sections with hexagonal steel bars and bent 90 degrees to form a hexagon socket head bolt.
The hexagon socket head bolt is generally made of stainless steel, and a layer of antioxidant is formed on the surface. The material is added with molybdenum, which has good corrosion resistance, wear resistance, and rust resistance and the strength can reach 4.8. It is often used in general cold room processing and drawing, and its corrosion resistance is well used in the production of seawater and some chemical media. The round stainless steel hexagon socket head bolt can play a good anti-corrosion effect even when used in damp water. There is no residual burr on the surface, and it is not easy to slip when fixed and rotating. The deep design of the thread is more uniform during use. Sharper, to achieve a firm effect.
