The name of the wall Screw is directly translated from the English Drywall Screw. Its biggest feature in appearance is the horn head shape, which is divided into double line fine tooth drywall screw and single line coarse tooth drywall screw. The biggest difference between the two is that the thread of the former is double thread, which is suitable for the connection between the gypsum board and the metal keel with a thickness of no more than 0.8mm. The latter is suitable for the connection of gypsum board and wooden keel.

Drywall screw series is one of the most important categories in the whole fastener product series. The product is mainly used in various gypsum board, light partition wall and ceiling ceiling series installation. Phosphating drywall screws are the most basic product system, and blue and white zinc drywall screws are a supplement, and the scope of application and purchase price of the two are basically the same. The slight difference is that the black phosphating has a certain lubricity, and the attack rate (the speed of entering the specified thickness of the steel plate, which is a quality assessment index) is slightly better; The blue and white zinc is slightly better in the anti-rust effect, and the color of the product is light, and it is not easy to pan color after paint decoration.

There is almost no difference in rust prevention ability between blue and white zinc and yellow zinc, only in the difference of use habits or user preferences. The thread of the single-line coarse teeth drywall screw is wider, the corresponding attack speed is faster, and because it will not destroy the structure of the wood material itself after entering the wood, it is more suitable for the installation of the wooden keel than the double-line fine teeth drywall screw.

In foreign countries, the general construction attaches great importance to the selection of suitable fastener products, single line coarse teeth drywall screws are more suitable for use in the connection of wood keel as an alternative to double line fine teeth drywall screws. In the domestic market, double-line fine teeth drywall screws have been used for a long time, and the change of use habits takes a certain amount of time.
