Refined Phosphating Dry Wall Nail - High-Quality Gypsum Board Screws from China Suppliers and Factory
Fine ThreadProducts
Phosphated dry wall screws are the most basic product line, while blue and white zinc dry wall screws are a supplement, and their scope of application and purchase price are basically the same. Slightly different is that black phosphating has a certain degree of lubricity, and the attack speed (the speed of entering a specified thickness of steel plate, which is a quality assessment indicator) is slightly better; Blue and white zinc have a slightly better rust prevention effect, and the product's natural color is light, making it less likely to fade after coating decoration.
There is almost no difference in rust prevention ability between blue white zinc and yellow zinc, only due to differences in usage habits or user preferences.
Single line coarse teethproducts
The thread of a single thread coarse tooth dry wall screw is wider, and the corresponding attack speed is also faster. At the same time, because it does not damage the structure of the wood material itself after entering the wood, it is more suitable for the installation of wooden keel than double thread fine tooth dry wall screws.
In foreign countries, construction generally places great emphasis on selecting suitable fastener products. Single line coarse tooth dry wall screws are a substitute for double line fine tooth dry wall screws and are more suitable for use in the connection of wooden keels. For a long time in the domestic market, double line fine tooth dry wall screws have been used entirely, and changing usage habits requires a certain amount of time.
Frequently Asked Questions
What is the difference between black phosphated and blue white zinc dry wall screws?
Black phosphating provides a certain degree of lubricity and a slightly better attack speed. Blue and white zinc screws offer a slightly better rust prevention effect and are less likely to fade after coating decoration due to their light natural color.
Is there a performance difference between blue white zinc and yellow zinc dry wall screws?
There is almost no difference in rust prevention ability between blue white zinc and yellow zinc. The choice between them is mainly determined by usage habits or user preferences.
Why are single line coarse tooth dry wall screws better for wooden keels?
Single line coarse tooth dry wall screws have wider threads that allow for faster installation (attack speed). More importantly, they do not damage the structure of the wood material itself upon entering, making them highly suitable for wooden keel installations.
What is meant by "attack speed" in dry wall screws?
Attack speed is a quality assessment indicator that measures the speed at which a screw enters a specified thickness of steel plate.
How does the market usage of single line coarse teeth compare to double line fine teeth screws?
In international markets, construction standards place a high emphasis on using single line coarse tooth screws for wooden keels. However, in the domestic market, double line fine tooth screws have historically dominated, meaning transitioning to coarse tooth screws requires time to change user habits.
