When using carbon steel screws, the following matters needing attention:
Avoid acid and alkali environments: Carbon steel screws are prone to rust in acid and alkali environments, so carbon steel screws should be avoided in these environments.
Correct installation and operation: During installation, ensure that the threaded holes are flat and the threads fit tightly to avoid rapid impact lifting. Use appropriate tools (such as torque wrenches or socket wrenches) to operate, and avoid over-tightening to cause damage or biting of the screws. During installation, keep the center axis of the screw perpendicular to the locked surface to reduce the deflection angle.
Lubrication and rust prevention: Lubricant can be applied before use to keep the threads clean and reduce the friction coefficient. Carbon steel screws themselves do not require additional lubrication, but it is recommended to apply anti-rust oil in humid environments to extend their service life. Anti-rust treatment methods include galvanizing, nickel plating, phosphating and painting.
Storage conditions: The storage environment needs to be dry and ventilated to avoid excessive humidity. The screws should be placed on the bracket to avoid direct contact with the ground.
Environmental adaptability: Carbon steel screws are suitable for use within room temperature, but the manufacturer should be consulted in high temperature (>400℃) or low temperature (<0℃) environments. Carbon steel screws are prone to rust in harsh environments such as humidity, high temperature, acid and alkali, and anti-rust measures need to be taken.
Regular inspection and maintenance: Regular internal safety inspections and professional inspections are carried out to observe signs of thread damage and deformation. After installation, the tightening state of the screws needs to be checked regularly to prevent loosening.
Avoid overtightening: Overtightening may cause damage to the screws or reduce the load-bearing capacity of the connector. Tighten the screws with appropriate torque to avoid breaking the screws due to excessive force.
