Fastening metal fasteners in parts often because of various reasons for the occurrence of corrosion, corrosion in some fasteners will be completely locked, causing the fastener itself operating loss of performance which is unable to remove or continue to lock fastener. The complete locking of the fastener may occur only in a matter of seconds, so a more accurate understanding and use of fasteners will be necessary to prevent locking.
1, fastener locking reason
The lock fastener is generally made in stainless steel or alloy material products, this is because the metal material itself has the ability of anti-corrosion, once the metal surface fastener damage will appear oxide layer to provide protection against corrosion increased, but when the fastener is locked that force generated by pressure and heat will destroy the oxide layer, the metal block or shear thread, and occurrence of adhesion phenomenon, it is locked.
2, fasteners to avoid locking method:
* This fastener lock does not completely eliminate, but we can reduce the probability of lock occurs by paying attention to various factors, such as to ensure the load capacity of fasteners, screws and nuts to choose more tensile strength etc..
* This thread fastener is clean but also on whether to lock effect when the thread is rough or not clean, lock more often, so be sure to fasteners cleaning before use to remove iron or dirt.
* Fasteners in correct and proper lubrication after processing, metal parts due to force the heat generated will be reduced effectively, so it will correspondingly reduce the fastener lock situation appears.
*use the washer and fastener installation in the right way, there is less lock.http://www.lwhardware.com/
