Grade 12.9 socket head cap screws are the most commonly used series of high strength screws: Grade 12.9 socket head cap screws are generally used in cases with high mechanical performance requirements. Such as injection molding machines, hydraulic equipment, mold and other places. The surface hardness of 12.9 grade socket head cap screws after heat treatment can reach 39-44 degrees.


The surface of the 12.9 grade socket head cap screws is cyanidated and blackened, and the product itself also has a certain anti-rust function. However, these high-strength Grade 12.9 screw series are mainly used in some equipment for export. During transportation, some relatively harsh environments will corrode the surface of Grade 12.9 socket head cap screws (such as shipping). And some appliances themselves require the matching products with socket head cap screws to be nickel-plated and electroplated to improve the corrosion resistance and appearance of 12.9 high-strength screws (such as bread machines, bakers, etc.).
