Solution to avoid rust of self tapping screws

1. In terms of electroplating process, the electroplating color with a longer salt spray test time should be selected. During electroplating, the electroplating should be good, and the electroplating layer should not be too thin. Moreover, in order to further improve the anti rust ability, we can consider spraying imitation rust paint.
2. In terms of storage environment, place the packaged self tapping screws on the tray or shelf without contacting the bottom. The storage environment should not be too wet. It should be ventilated and breathable without too much water vapor.
