Bugle Head Drywall Screws Black Phosphated Coarse Thread Drywall Screw

Bugle Head Black Phosphated Coarse Thread Drywall Screw Black

1,Description:

Drywall screws are a type of nail. Their name is directly translated from the English word "Drywall Screw". The most distinctive feature in appearance is the horn head shape. They are divided into double-thread fine-thread drywall screws and single-thread coarse-thread drywall screws. The biggest difference between the two lies in that the thread of the former is double thread.

Phosphating dry-wall screws are the most fundamental product series, while blue and white zinc dry-wall screws are a supplement. The application scope and purchase price of these two are basically the same. The only slight difference is that black phosphating has a certain degree of lubricity, and the attack speed (the speed of penetrating steel plates of a specified thickness, which is a quality assessment index) is slightly better. Blue-white zinc has a slightly better anti-rust effect, and the natural color of the product is light, making it less likely to show color after coating decoration.

4,Feature Advantage:

There is almost no difference in rust prevention ability between blue-white zinc and yellow zinc. The only difference lies in the usage habits or the preferences of the users

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

Abroad, in general construction, great emphasis is placed on choosing the right fastener products. Single-line coarse-threaded dry-wall screws, as an alternative to double-line fine-threaded dry-wall screws, are more suitable for use in the connection of wooden keels. In the domestic market, double-line fine-thread dry-wall screws have been used exclusively for a long time. It takes some time to change the usage habits
