In daily life, stainless steel bolts are very common fasteners. In the application process, people often encounter the following problems, and how to solve them? loose problem When using stainless steel screws, screw looseness is a very common problem. Under certain shocks and vibrations, they will become settled and loosened. It can be treated with anti-falling glue or anti-loosening with spring pads. blackening problem The reason for the blackening of stainless steel screws is that during the process of rubbing or cold heading, the screws generate too much heat, and the material of the screw itself will also cause the screws to blacken. The blackened parts are mainly manifested in the cross groove. This requires the electroplating factory to pay attention to quality control when cleaning. Corrosion and rust problems Stainless steel screws will also corrode and rust, which will cause corrosion and rust of stainless steel screws mainly include: carbon dioxide, sulfuric acid and other substances in the air will cause screw corrosion, dust and moisture in the air will cause chemical corrosion, and the surface of the screw will stick Attached organic matter, after a period of time, can also cause the screws to rust. This should be based on the actual situation to choose the corresponding material and surface treatment. cracking problem Generally, stainless steel screws are not easy to crack. The main reason for screw cracking is poor material quality, or unreasonable processing technology may lead to screw cracking. Qualified materials and processing techniques should be selected.
