Learning more about the hex socket bolt:
Hexagon socket head cap screw, also referred to as hexagon socket head bolt, cup head screw, hexagon socket head screw, its name is different, but the meaning is the same.
Generally, the commonly used six point socket head cap screws are grade 4.8, grade 8.8, grade 10.9 and grade 12.9. It is also called hexagon socket screw, also called hexagon socket bolt. Its head is hexagonal and cylindrical. There are stainless steel and iron according to the material. There are stainless steel SUS202 hexagon socket head cap screws in stainless steel. This is made of stainless steel.
There are stainless steel SUS304 hexagon socket head cap screws and stainless steel SUS316 hexagon socket head cap screws. According to the strength grade of hexagon socket head screws, there are 4.8-grade hexagon socket head screws, 8.8-grade hexagon socket head screws, 10.9-grade hexagon socket head screws and 12.9-Grade hexagon socket head screws. Grade 8.8-12.9 hexagon socket head cap screws are high strength and high grade hexagon socket bolts.
- The nominal tensile strength of bolt material reaches 400MPa;
- The yield strength ratio of bolt material is 0.6; the nominal yield strength of bolt material is 400 × 0.6 = 240mpa.
The performance grade is 10.9 high strength bolt, and the material can reach the following after heat treatment:
- The nominal tensile strength of bolt material is up to 1000MPa;
- The yield strength ratio of bolt material is 0.9; the nominal yield strength of bolt material is 1000 × 0.9 = 900MPa.
The meaning of performance grade of hexagon socket head bolt is the international general standard. For bolts with the same performance grade, the performance is the same regardless of the difference of material and place of origin. Only the performance grade is selected in design.
The classification of hexagon socket bolts is basically like this. The market price will definitely be different with different grades. Generally, the price of high-strength socket head bolts is much higher than that of common socket head bolts. In the market, there are generally 4.8, 8.8, 10.9 and 12.9 grades.
The head of the socket head bolt is eccentric and crooked, which may cause serious problems. For example, in terms of product appearance, it is not beautiful as a whole. There is also eccentric play, it is easy to lead to the production tool punching pin easily broken. The most serious problem is the break of hexagon bolt and so on.
