Security screw which made of iron even have electroplate but also easy to get rusty. What’s the reason of security screw get rusty, I would like to share some experience about that. Let’s have a look at it.

During production of security screw, some measures will easy to make screw get rusty. Firstly, when electroplating factory electroplate security screw, doesn’t dry screw enough, which will led to steam still remain on the surface, or packing after drying there is condensation water in the package. These two kinds of behavior can cause chemical reaction to make screw get rusty. Secondly, long store in a wet place and with time goes by, security screw slowly corrode, then exist severe oxidative, thus lead to rusty. Thirdly, there is defective plating when electroplating, the coat is too thin to cause rusty. Well, there are the 4 reason of security screw get rusty. All in all, when we analyze the cause of screw get rusty, 4 direction can be thinking about: store environment, plating types, way to preserve, and using environment.

Security screw fasteners are important for us daily life. So we can aim at these 4 reason to do some improvement to prevent. About store environment, we should store security screw in the right circumstances, must not too wet, and must keep ventilation and dry. You can use a support to store screws, avoid contacting with the ground. About plating types, we can select those copper plating which have a long salt spray time. Do a well electroplating and shouldn’t make a thin coat. About using environment, should not use in a high salinity, high acidity, high corrosion, high temperature, and high humidity environment.

Well, do you see reason about security screw get rusty? I will share other information about security next time. So stay tuned, thanks.
