Steel A2 70 Phillips Drive Slotted Round / Pan Head Machine Screws

 

Description:

 

High strength large hexagon head bolt combination screw for steel structure, mainly used in railway and highway Bridges, boiler steel structure, industrial plant, high-rise civil buildings, tower mast structure, hoisting machinery and its steel structure need to use friction type high strength bolt combination screw.Its characteristic is bolt, namely the end that calls bolt is much a dodecahedral body.Installation, the use of special electric wrench, the upper and lower has two socket head, one set on the hexagon nut, the other set on the outer hexagon screw ten corners.When tightening, apply clockwise torque to the nut, and apply equal counterclockwise torque to the dodecagon body of the bolt, so as to make the connection between the end of the outer hexagon screw and the dodecagon body to bear the torsion shear, until the neck is cut off, the installation is finished.This kind of twisted shear type high strength external hexagon screw is a type of screw for primary use, after installation can not be removed.

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.
