    High tensile Stainless steel ss304 / 306 Round head sems screw

     

     

    Description:

     

    The quality of combination screw should start from the combination screw manufacturer's screw wire.Screw wire is the first key to determine the quality of composite screw. The wire is not good, even if the production equipment is advanced and the staff is skilled, they cannot produce high-quality composite screw.In the second look at the combination of screw product quality from the combination of screws overall aesthetics.A combination screw is formed, the size of the head of the screw, the superior appearance of the flat pad, the screw thread can pass through the stop gauge, etc.These are all things that need to be detected.A good combination of screws, the overall standard can meet the requirements of national standards, or customer requirements.Finally, the quality of composite screw products is seen from the color of electroplating. Of course, the composite screw of iron needs electroplating, but the composite screw of stainless steel does not need.Some is at most passivation, in order to increase the combination of stainless steel screws to carry salt fog.Combination screw electroplating color, some do not control well, will produce a large color difference.It's not very nice.

    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.
