304 / 316 Stainless Steel Cross Round Head Machine Screws
Generally speaking, the combination screw is widely used in electrical, electric, mechanical, electronic, household appliances, furniture, ships and so on.But it says different combination screws have different effects.Cross - disc head combination screws, for example, are commonly used in small electronic products.Large cross hexagon combination screw used in large electrical products, such as frequency converter, some large frequency converter is useful to a lot of cross hexagon combination screw.Hit the converter housing.To loosen or tighten.In such as with the tooth two combination screw, this is used in the frequency converter, the role is used to break paint, make the housing plate surface of the two combination screw are all electrified.There are also such as the square pressure line two combination screw, which itself is a disc head screw with a square pad of two combination screw.It is usually applied to the terminal on the surface.It's used for wiring, it's used for pressing wires.

The first is the hardness of the hexagon socket head cap screws:
Hexagon socket head cap screws are classified according to the tensile strength, yield strength and hardness of the screw wire. So to a certain extent, the bolts are of a number of materials, and the same screws are required for the selected screws. Generally speaking, the hexagonal bolts can be divided into two types according to the grade strength. One is common and the other is high strength. The ordinary hexagon socket bolts are usually 4.8, while the high-strength hexagon socket bolts refer to The above grade 8.8 is called a high-strength bolt. Among them, the 12.9 grade hexagon socket bolts are knurled and the color is natural.
The second is the performance requirements of the hexagon socket head cap screws:
The material of the hexagon socket screw can reach 400MPa in tensile strength, the yield ratio of the screw material is 0.6, and its nominal yield strength can reach 240MPa. The high-strength hexagon socket head cap screws with a performance class of 10.9 have a nominal tensile strength of 1000 MPa, a screw yield ratio of 0.9, and a nominal yield strength of the screw of 900 MPa. In general, the hexagon socket head cap screws are all internationally accepted. The same grade of screws, regardless of its thoroughness and material quality, is identical in performance. Be careful not to smash the head of the hex screw during use.
The third is the use of hexagon socket head cap screws and other specifications:
The hexagon socket head cap screw is very similar to the countersunk head screw. When the nail head penetrates into the machine part, its connection strength is very large, so the corresponding size of the hex wrench must be used during use. The screws are attached and detached. Generally used in a variety of machine tools and its accessories, the international standard for hexagon socket head screws is GB70-1985. The common specifications are 4*30, 4*35, 4*45, 5*10. , 5*12, 5*16, 5*20, 5*25, 6*12, 6*14, 6*16, 6*25, 8*14, etc.
