    Hex Socket Cup Head Sem Stainless Steel Machine Screws Cold Forging Process


    Hex Socket Cup Head Sem Stainless Steel Machine Screws Cold Forging Process


    Description:


    The hexagonal head cap screws, also referred to as hexagon socket head bolts, cup head screws, and hexagon socket head screws, are not the same, but the meaning is the same. Commonly used hexagon socket head cap screws are also 4.8, 8.8, 10.9, 12.9. Also called a hexagon socket screw, also called a hexagon socket bolt. Its head is a hexagonal head and is also a cylindrical head. Divided into stainless steel and iron by material. Stainless steel is made of stainless steel SUS202 hexagon socket head cap screws. This is made of stainless steel. It is made of stainless steel SUS304 hexagon socket head cap screws and stainless steel SUS316 hexagon socket head cap screws. The iron has a hexagonal cylinder head screw strength grade. It has a 4.8-stage hexagon socket head cap screw, a 8.8-stage hexagon socket head cap screw, a 10.9-level hexagon socket head cap screw, and a 12.9-stage hexagon socket head cap screw. The 8.8-grade-12.9 hexagon socket head cap screws are called high-strength and high-grade hexagon socket head bolts. Standard No. StandardNo: GB/T 70.1-2008.

    DescriptionHigh-quality, rich manufacturing experience

    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.
