     sting dry wall screw is the most basic product, while blue white zinc dry wall screw is a supplement. The application scope and purchase price of the two products are basically the same. The slight difference is that black sting has a certain lubricity, and the attack speed (the speed of entering the steel plate with the specified thickness, which is a quality assessment index) is slightly better; while blue white zinc is slightly better in the anti rust effect, and the product's natural color is light, so it is not easy to pan color after coating decoration.

There is almost no difference between blue white zinc and yellow zinc in antirust ability, only because of different usage habits or user preferences.
