Metal fasteners in fasteners are often corroded for various reasons. When corrosion occurs, some fasteners will be completely locked, resulting in the failure of the operation of the fastener itself, that is, it cannot be disassembled or locked. on the fasteners. The complete locking of fasteners may only occur within a few seconds, so it is necessary to recognize and use fasteners more correctly to prevent locking.

How to reduce the probability of stainless steel fasteners locking

Metal fasteners in fasteners are often corroded for various reasons. When corrosion occurs, some fasteners will be completely locked, resulting in the failure of the operation of the fastener itself, that is, it cannot be disassembled or locked. on the fasteners. The complete locking of fasteners may only occur within a few seconds, so it is necessary to recognize and use fasteners more correctly to prevent locking.

1. The reasons for the locking of fasteners

The locking of fasteners generally occurs on products made of stainless steel or alloy materials, because these metal materials themselves have the ability to prevent corrosion. Once the metal surface of the fastener is damaged, oxidation will occur. However, when the fastener is tightened, the pressure and heat generated by the force will destroy the oxide layer, causing blockage or shearing between the metal threads, and then sticking. is locked.

2. The method of fasteners to avoid locking:

★The locking of fasteners is not complete, but we can reduce the probability of locking by paying attention to various factors, such as ensuring the load capacity of the fasteners, choosing screws and nuts with higher tensile strength, etc.

★Whether the thread of the fastener is clean also has a certain influence on whether it is locked or not. When the thread is rough or unclean, the locking is more common. Therefore, it is necessary to ensure the cleaning of the fastener before use and remove the iron filings. or dirt.

★After the fasteners are properly and properly lubricated, the heat generated by the force of the metal parts will be effectively reduced, which will correspondingly reduce the probability of the fasteners locking up.

★ Fasteners are also less likely to lock up when they use washers and are installed in the correct way.
