How To Reduce The Probability Of Cap Screw Lock

    Cap screws often rust due to various reasons. Some [u]Cap Screw[/u] may become completely locked when rust occurs, resulting in the failure of the cap screw itself to operate, that is, the cap screws cannot be removed or continue to be locked. The complete locking of the cap screw may only occur within a few seconds, so it is necessary to know and use the cap screw more correctly to prevent the lock from occurring.
    1, the reason for the cap screw lock
    The locking of the cap screws usually occurs on products made of stainless steel or alloy materials. This is because these metal materials have the ability to resist rust. Once the metal surface of the cap screws is damaged, an oxide layer will appear. Provide protection against corrosion, but when the cap screw is locked, the pressure and heat generated by the force will damage the oxide layer, causing blockage or shearing between the metal threads, and then sticking, that is, locking .
    2, the cap screw to avoid locking method:
    The locking of the cap screw can not be completely eliminated, but we can reduce the probability of locking by paying attention to various factors, such as ensuring the load capacity of the cap screw, and selecting the screw and nut with more tensile strength.
    Whether the thread of the cap screw is clean or not has a certain influence on the lock. When the thread is rough or not clean, the lock is more common. Therefore, make sure the cap screw is cleaned before use to remove iron filings or dirt. .
    After the cap screw is properly and properly lubricated, the heat generated by the force of the metal part is effectively reduced, which will reduce the probability of the cap screw locking.
    Locking is also less likely when the cap screw is installed in the correct way and is installed in the correct way.
