Which three problems should be paid attention to in the maintenance of fasteners

Although fasteners are small, they have great effects. The use of fasteners requires regular maintenance to ensure safer use of fasteners, extend the service life of fasteners, and improve the performance of mechanical equipment.

When we are maintaining fasteners, there are three main problems:

1. When the fastener is quenched, use a silicate cleaning agent to clean up the impurities, and then rinse carefully to avoid leaving impurities on the fasteners, affecting its Normal application. (Guide: There are skills in selecting materials for stainless steel screws)

2. After the fastener is tempered, its color may change. After the fastener is soaked in ether for a period of time, oily substances will be produced. This situation indicates The fasteners are not clean enough. After the analysis, it is found that the stacking of fasteners is not very reasonable when heating the fasteners, and the fasteners may have some small oxidation phenomena in the quenching oil.

3. If there is a white substance on the fastener, it is likely to be some phosphide. The reason for this phenomenon is that the acid cleaning machine is not used for cleaning, and the rinsing tank is not carefully checked.

The above problems must be paid attention to. They will directly affect the performance of the fasteners, and may also reduce the service life of the fasteners and cause the phenomenon of early damage to the fasteners.
