Brief Introduction of Drywall Screws

Drywall screws are a kind of screws. The biggest feature in appearance is the shape of the horn head. It is divided into double line fine tooth drywall screws and single thread thick drywall screws. The two are the largest difference is that the thread of the former is a double thread. It is suitable for the connection between gypsum board and metal keel whose thickness does not exceed 0.8mm, and the latter is suitable for connection between gypsum board and wooden keel.

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 ceilings.

Double thread fine teeth screws

Phosphating 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 degree of lubricity, and the attack speed (the speed at which the steel plate of a specified thickness is penetrated, which is a quality assessment index) is slightly better; while the blue and white zinc is slightly better in anti-rust effect, and The natural color of the product is light, and it is not easy to fade after paint decoration.

There is almost no difference between blue and white zinc and yellow zinc in anti-rust ability, only because of the difference in usage habits or user preference.

Single thread coarse teeth screws

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