After the black double end threaded bolt is treated with black anti-corrosion, a layer of oxide is formed on its surface, which has certain anti-corrosion and anti-oxidation capabilities. Therefore, it is less likely to rust in the short term than ordinary bolts. However, long-term contact with the external environment, such as humid air, water vapor, oxygen, etc., will cause oxidation reaction on the surface of the double end threaded rod and produce rust, so the rust of the double end threaded stud cannot be completely avoided.
double end threaded stud bolts strip maintenance
In order to extend the service life of the double end threaded screw and ensure the safety and stability of the mechanical equipment, the care and maintenance of the double end thread is very important. The following points are recommended:
1. Choose high-quality double end threaded stud screw bolt to avoid small defects in the double end threaded bolt due to poor quality, which will affect the service life.
2. During use, try to avoid impact, bending and other actions to reduce its stress and extend its life.
3. During installation and use, avoid exposing the threaded rod to severe corrosive substances such as moisture and salt. Especially in a humid environment, clean and apply anti-rust substances such as paint and blue nylon lock nuts in time to protect the surface of the black bolt.
4. Regularly check and replace damaged or rusted bolts. It is more reliable to use bolts with rust-proof function.
