The so-called Full Threaded Stud hardening refers to the hardening of the screws required by the customer. Hardening is what we often call heat treatment. The need to harden means to heat the screws.
Screw hardening is also called quenching. Quenching can increase the hardness, but the screw needs toughness, high tensile strength, and does not require high hardness. Therefore, in general, screws need to be quenched and tempered at high temperature, also called quenching and tempering treatment, to enhance the tensile strength of the screw. The simple understanding is to harden the screw and add the hardness of the screw itself.
Why should the screws be hardened? The main reason is that if many screws are not used before hardening, it is easy to slip or break their ends. Therefore, adding the step of hardening the screws and hardening the screws can solve the problem of screw sliding and broken screws. .
Generally speaking, only iron screws are stainless steel screws that need to be hardened. Hardening treatment is rarely done. But if the customer requires the stainless steel screw to be hardened, then just do it according to the customer’s request. The high-strength screws themselves have been hardened with wires, and the hardness is relatively high, but some still need to be hardened to reach this level of high strength.
Therefore, in order to have a better quality of use of screws, China Fasteners will harden the screws that need to be hardened to meet customer requirements.
