Drywall screw with black or gray color we can provide. Drywall Screw Introduction  Its biggest feature in appearance is the shape of the horn, which is divided into two-line thin-tooth dry-wall screws and single-line thick-tooth dry-wall screws. The biggest difference between the two is the former. The thread is a double thread, suitable for the connection between gypsum board and metal keel with a thickness not exceeding 0.8mm, while the latter is suitable for the connection between gypsum board and wooden keel. The drywall 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 plasterboards, lightweight partition walls and ceilings.  double line fine teeth Phosphate drywall screws are the most basic product line, and blue and white zinc drywall screws are a supplement. The scope of application and purchase price of the two are basically the same. The slight difference is that black phosphating has a certain lubricity, and the attack speed (the speed of breaking into a steel plate of a specified thickness is a quality assessment index) is slightly better; while the blue and white zinc is slightly better in the rust prevention effect, and The natural color of the product is light, and it is not easy to pan color after coating decoration. Blue and white zinc and yellow zinc have almost no difference in rust prevention ability, but only in different usage habits or user preferences. Single line coarse teeth The single-thread coarse-wall drywall screw has a wider thread and a faster attack speed. At the same time, the structure of the wood material will not be damaged after the wood is inserted, so it is more suitable for the installation of wood keel than the double-line fine-wall drywall screw. In foreign countries, construction generally pays great attention to the selection of suitable fastener products. Single-line coarse-tooth dry-wall screws are an alternative to double-line fine-tooth dry-wall screws and are more suitable for use in the connection of wooden keels. In the domestic market, double-line fine-tooth drywall screws have all been used for a long time, and it takes a certain time to change the usage habits.
