Cylindrical head hex socket screws, also known as hex socket bolts, cup head screws, and hex socket screws, have different names but represent the same meaning. The commonly used hexagon socket cylindrical head screws also include grades 4.8, 8.8, 10.9 and 12.9. It is also called an Allen screw or an Allen bolt. Its head is an Allen head and also a cylindrical head. They are classified by material into stainless steel and iron. There are stainless steel SUS202 hexagon socket cylindrical head screws. This is a common stainless steel material, including stainless steel SUS304 hexagon socket cylindrical head screws and stainless steel SUS316 hexagon socket cylindrical head screws. According to the strength grade of the hexagon socket cylindrical head screws, there are 4.8 grade hexagon socket cylindrical head screws, 8.8 grade hexagon socket cylindrical head screws, 10.9 grade hexagon socket cylindrical head screws and 12.9 grade hexagon socket cylindrical head screws. Hex socket cylindrical head screws of grade 8.8 to 12.9 are called high-strength and high-grade hex socket bolts.
Quality inspection
Performance requirements
The nominal tensile strength of the bolt material reaches the 400MPa grade.
2. The yield-to-tensile ratio of the bolt material is 0.6. The nominal yield strength of the bolt material reaches 400×0.6=240MPa grade.
High-strength bolts with performance grade 10.9, after heat treatment of their materials, can achieve:
The nominal tensile strength of the bolt material reaches the 1000MPa grade.
2. The yield-to-tensile ratio of the bolt material is 0.9. The nominal yield strength of the bolt material reaches 1000×0.9=900MPa grade.
