Its biggest feature in appearance is the Bugle head shape, which is divided into double-thread fine-thread drywall screws and single-thread coarse-thread drywall screws. The biggest difference between the two is that the thread of the former is double thread, which is suitable for gypsum boards with a thickness of no more than 0.8 mm metal keels, while the latter is suitable for the connection between gypsum boards and wooden keels.

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

Phosphated drywall screws are the most basic product series, while 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 degree of lubricity and the attack speed (the speed of penetrating a steel plate of a specified thickness, which is a quality assessment index) is slightly better; while blue and white zinc has a slightly better anti-rust effect, and The natural color of the product is light, and it is not easy to discolor after being decorated with paint.

There is almost no difference in anti-rust ability between blue and white zinc and yellow zinc, it just depends on the usage habits or the user’s preference.

The threads of single-thread coarse-thread drywall screws are wider and the corresponding attack speed is faster. At the same time, since the structure of the wood material itself will not be damaged after tapping into the wood, it is more suitable for the installation of wooden keels than double-thread fine-thread drywall screws.

In foreign countries, general construction pays great attention to the selection of suitable fastener products. Single-thread coarse-thread drywall screws are an alternative to double-thread fine-thread drywall screws and are more suitable for use in the connection of wooden keels. In the domestic market, all double-threaded fine-thread drywall screws have been used for a long time, and it will take some time to change the usage habits.
