Hexagon head bolt is a common machine screw, which has the advantages of easy to dismantle and not easy to slip off. A hex key is usually 90 degrees, with one end long and one short. When using short screws, holding the long side saves a lot of effort and tightens the screws better. The manufacturing cost of hexagon socket head bolts is much lower than that of socket socket head bolts. The advantage is that they are thinner than hexagon socket head bolts (where the wrench is stressed), and there are some hexagon heads that cannot be replaced by hexagon socket heads.

Also, a low-cost, low-power-strength, low-precision machine requires fewer socket head bolts than socket head bolts. Hexagon socket head bolts are also called hexagon socket head bolts, also known as hexagon socket head bolts. They are screws with a hexagonal inner hole on the head. After the hexagonal wrench is inserted into the inner hole, it can be tightened or released. Ordinary hexagon socket head bolts are cylindrical head screws with a head diameter of about 1.5 times the main diameter of the thread. Other heads include cap screws for an aesthetically pleasing finish and countersunk head screws for tapered threaded holes. The recessed design allows the screw head to rotate without exposing the surface to the fixed object, so it is often used on smaller surfaces and where conventional wrenches are inconvenient.

Outer hexagon bolts are divided into inner hexagon bolts and outer hexagon screws, which are generally used for the fastening of mechanical equipment. Hex head bolts are externally threaded fasteners with a hex head for wrench rotation. The hexagon head bolt has a round head on the outside and a concave hexagon in the middle, while the outer hexagon screw is a common bolt with a hexagon head. The hexagon socket head bolt is shaped like a "7", and is cut into two sections by hexagonal steel bars and bent into a 90-degree socket head screw wrench. Hexagon bolts are generally made of stainless steel, and a layer of antioxidants is formed on the surface. After adding molybdenum, the material has good corrosion resistance, wear resistance and rust resistance, and the strength reaches 4.8.

In the production of seawater and some chemical media, it is often used in general cold room processing and drawing, and has good corrosion resistance. The round stainless steel hexagon head bolts have a good anti-corrosion effect even when used in wet water; there is no residual burr on the surface, and it is not easy to slip when rotating, and the depth design of the thread is more uniform during use, and the thread teeth are sharper , so as to achieve a solid effect.
