Refined Phosphating Dry Wall Nail

The biggest feature of drywall screws in appearance is the horn shaped shape, which is divided into double line fine tooth drywall screws and single line coarse tooth drywall screws. The biggest difference between the two is that the former has double threads and is suitable for connecting gypsum boards with metal keels with a thickness not exceeding 0.8mm, while the latter is suitable for connecting gypsum boards with wooden keels.

The dry wall screw series is one of the most important categories in the entire fastener product line. This product is mainly used for the installation of various gypsum boards, lightweight partition walls, and ceiling suspension series.

    Phosphated dry wall screws are the most basic product line, while blue and white zinc dry wall screws are a supplement, and their scope of application and purchase price are basically the same. Slightly different is that black phosphating has a certain degree of lubricity, and the attack speed (the speed of entering a specified thickness of steel plate, which is a quality assessment indicator) is slightly better; Blue and white zinc have a slightly better rust prevention effect, and the product's natural color is light, making it less likely to fade after coating decoration.

    There is almost no difference in rust prevention ability between blue white zinc and yellow zinc, only due to differences in usage habits or user preferences.

    Single line coarse teethproducts

    The thread of a single thread coarse tooth dry wall screw is wider, and the corresponding attack speed is also faster. At the same time, because it does not damage the structure of the wood material itself after entering the wood, it is more suitable for the installation of wooden keel than double thread fine tooth dry wall screws.
    In foreign countries, construction generally places great emphasis on selecting suitable fastener products. Single line coarse tooth dry wall screws are a substitute for double line fine tooth dry wall screws and are more suitable for use in the connection of wooden keels. For a long time in the domestic market, double line fine tooth dry wall screws have been used entirely, and changing usage habits requires a certain amount of time.
