Common problems of stainless steel screws

In daily life, we always can't avoid using stainless steel screws to install something, but sometimes the following problems occur:

(1) screws loosened issues: When using stainless steel screws, a common problem is that the screws are loose. When the screw is subjected to shock or vibration during use, it will loosen.
(2) Screw blackening: The blackened part is generally the groove. The main reason for the blackening is that the screw generates excessive heat during the process of cold heading or threading. Another possibility is that the raw material of the screw is not good, which causes the screw to turn black.

(3) Corrosion and rust: Stainless steel screws will also rust under long-term external environmental corrosion, especially in the case of more dust or humidity in the air, which will accelerate the corrosion and rust.
(4) Cracking and fracture: Generally speaking, stainless steel screws will not crack, but if the raw materials are not good, they may crack during use. Or the user exerts too much force when using the screw, which causes the screw to break.
