Maintenance Precautions For Special Screws

Special screws are small parts of the equipment, but to ensure the normal operation of the equipment, regular maintenance of special screws is essential. Due to the importance of special screws, to avoid problems, you need to pay attention to many aspects of the maintenance process, and as a professional fastener manufacturer, Xinchi is happy to share the maintenance precautions of special screws with you.

Remove debris: Special screws need to be cleaned by silicate after quenching and fully washed. To prevent residue and debris, it is necessary to be very careful during washing.

Avoid damage to special screws: Sometimes special screws will change color after heating treatment, and there may be oily residue after soaking in ether, which indicates that the surface of special screws is not clean. After analysis, it was found that this may be due to the improper stacking of special screws during heating, resulting in slight oxidation in the quenching oil.

Remove surface residue: High-strength screws that are not acid-cleaned and adequately rinsed may leave a white residue on the screws. Upon examination, it was found that it was probably phosphide.
