Hex socket head cap screws are classified according to the tensile strength, yield strength and hardness of the screw wire.

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 hex 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.

Performance characteristics

Powerful anti-loose function, in line with the IFI524 anti-loose torque standard (details can be requested by phone).

It can be reused and still has its strong anti-loosening properties after repeated use.

It can be used at high temperature and low temperature. The normal use temperature is -50°-125°. Please call us if it exceeds this temperature. We will deal with it according to special requirements.

All materials are environmentally friendly and can provide reports on SGS, ROHS, halogen, etc.

Performance requirements for 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 the international standard. The same grade of screws, regardless of its thoroughness and material, are identical in performance. Be careful not to smash the head of the hex screw during use.
