Discussion on the Function of Hexagon Screw

Hexagon screws with insulation, visa, corrosion resistance, beautiful, not rust and other characteristics, modified engineering plastics in the use of strength, impact energy, metal and other aspects can be comparable. We often say that plastic screws generally add 30% glass fiber to nylon screws, and their mechanical properties are much better than ordinary nylon. The materials used in plastic screws are diversified and their performance is continuously improved.

What is the standard for 12.9 grade high strength screws?

Grade 12.9 high-strength screws did not circulate such high-strength screws in the early industrial development of our country. At that time, the industrial technology was still in its infancy, and this 12.9-grade high-strength screw required very accurate heat treatment technology to complete its performance index. At that time, there was no such technical condition in China. In fact, we often said that 12.9-grade high-strength screws, most of which refer to hexagon socket head cap screws.

Type of 12.9 grade high strength screw

Grade 12.9 high-strength screws are commonly used in high-strength bolt series. Grade 12.9 hex screws are usually used in situations where high mechanical performance requirements are required. Injection machines, hydraulic equipment, mold assembly, etc. The surface hardness of grade 12.9 hex screws can reach 39-44 degrees after heat treatment. The production standards of grade 12.9 hexagon screws refer to German standard DIN912, GB/T70.1, American standard and English standard
