How do i keep the screw from rusting?

The common phenomenon of screw in daily life is "rusting", which is not surprising to many fastener manufacturers. Do you know the reason why screw rusts and how to prevent it from rusting?


Let's find out why these screws are rusty:steel screws, stainless steel screws,shoulder screws,step screws,custom screws,steel screws


1. Far away from the humid environment, the impact of the humid environment on metal products can be said to be fatal, sunshine and rain, wind and rain, the speed of screw rusting are very fast, the most effective way is to place the screw in a dry and ventilated environment.


2. The corrosive effect of chemical substances. The chemical additives used in many special environments have a great impact on the products of a custom screw. Once the surface of screw is covered with these substances, such as strong acid, strong alkali and salt, it will cause local corrosion. For such problems, the most direct way for screw manufacturers is to strengthen the screw. Surface treatment, increase the protection of surface protective film, such as rust removal, spraying, passivation, electroplating, anodizing, electrophoresis, blackening, Dacromet and other surface treatment


3. In the polluted air environment, many external impurities are uncontrollable. These substances will contain a large number of sulfides, oxides and other substances. When they meet water, they will form strong sulfuric acid, nitric acid and other liquid points, which are easy to cause chemical corrosion. This requires not only choosing the correct storage environment but also doing inspectors at all times.


In the above three cases, it is very easy to rust. Therefore, more attention should be paid to the above three rusting factors in peacetime. In order to prevent the screw from rusting easily, the most important thing is to put the screw in a dry place, don't let the water mist liquid immerse, don't let the contaminated things touch, and then do the surface treatment
