    Description:

     

    Combination screw is actually a kind of screw, but in a special way, usually three combination or two combination, but at least two combination can be called combination screw.The difference with ordinary screws is the most important is more than ordinary screws with a spring pad or with a flat pad, in or is three combination pieces, with an additional spring pad.This is the main difference between the appearance of composite screw and normal screw.

    Combination screw and ordinary screw in addition to the appearance of the obvious difference, the main also has to be the difference between mechanical properties and USES.Combination screw is a combination of three or two parts with elastic flat pad, of course, it is made of ordinary screws with elastic flat pad.Put on the elastic flat pad, the elastic flat pad will not come off.Fastens and becomes a combination.From the mechanical performance, the combination of screws is three parts combination, performance is definitely the need for three fasteners together to make the role.The mechanical properties of the combined screw are more firm when used.More convenient, the combination of screws is the biggest advantage of the production line is convenient and fast operation, improve work efficiency.

    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.
