    Stainless Steel Cup Head Hexagon Socket Sem Combine Machine Screw


    Stainless steel hexagonal groove cup head assembly machine screw, also known as cup head screw and hexagonal socket head screw, although the name is different, it is only a product. The commonly used grades are 4.8, 8.8, 10.9 and 12.9. It has two kinds of head, one is a hexagonal head, the other is a cylindrical head. According to the material, it can be divided into stainless steel and iron. Stainless steel is made of stainless steel SUS202 hexagonal socket screw. It is made of stainless steel SUS304 hexagonal socket screw and SUS316 hexagonal socket screw. The iron has the strength grade of hexagonal cylinder head screw. It has a 4.8 level hexagonal sleeve head nut, an 8.8 level hexagonal sleeve head nut, a 10.9 level hexagonal sleeve head nut and a 12.9 level hexagonal sleeve head nut. The hexagonal sleeve head bolts of grade 8.8-12.9 are called high-strength and high-grade hexagonal sleeve head bolts. As a fastener manufacturer in China, our company has strict production procedures, quality assurance, and relevant inspection certificates, so that customers can get more protection. At the same time, our company can customize non-standard parts. Welcome to consult

    DescriptionHigh-quality, rich manufacturing experience

    The first 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 second 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 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.
