Refined Phosphating Drywall Nails - China Suppliers & Factory for Gypsum Board Installation
Fine Thread Products
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.
Single line coarse teeth products
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.
Frequently Asked Questions
Q What is the difference between phosphated and zinc dry wall screws?
Black phosphated screws offer a degree of lubricity and a slightly faster attack speed. Blue and white zinc screws provide slightly better rust prevention and have a light natural color that is less likely to fade after coating decoration.
Q What does "attack speed" mean for drywall screws?
Attack speed refers to the speed at which a screw enters a specified thickness of steel plate. It is a key quality assessment indicator for these fasteners.
Q Is there a difference between blue-white zinc and yellow zinc screws?
There is almost no difference in rust prevention capability between blue-white zinc and yellow zinc screws; the choice between them is typically based on usage habits or user preferences.
Q Why are single line coarse teeth screws better for wood keels?
Single line coarse teeth screws have wider threads that allow for a faster attack speed. More importantly, they do not damage the structure of the wood material itself, making them superior to double thread fine teeth screws for wooden keel installation.
Q How do domestic and foreign markets differ in drywall screw preferences?
Foreign markets place great emphasis on using single line coarse tooth screws for wooden keel connections. In contrast, the domestic market has long relied entirely on double line fine tooth screws, meaning transitioning to coarse thread screws requires time to change established habits.
