Refined Phosphating Drywall Nail - China Suppliers & Factory for Gypsum Board Installation Fasteners
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.
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.
Key Difference: Black phosphating offers superior lubricity and attack speed, while blue and white zinc provides enhanced rust prevention.
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.
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.
Wood Protection: Single line coarse thread screws prevent structural damage to wood, making them the ideal choice for wooden keel installations.
Frequently Asked Questions
What is the difference between phosphated and zinc dry wall screws?
Phosphated screws (black phosphating) offer a degree of lubricity and a slightly better attack speed. Blue and white zinc screws serve as a supplement, providing slightly better rust prevention and a light natural color that resists fading after coating decoration.
Is there a performance difference between blue white zinc and yellow zinc screws?
There is almost no difference in rust prevention ability between blue white zinc and yellow zinc screws. The choice between them is primarily determined by differences in usage habits or user preferences.
What is "attack speed" in dry wall screws?
Attack speed is a quality assessment indicator. It measures the speed at which a dry wall screw enters a specified thickness of steel plate.
Why are single line coarse teeth screws better for wooden keels?
Single line coarse teeth screws have wider threads that allow for faster installation. Additionally, they do not damage the structure of the wood material itself upon entry, making them far more suitable for wooden keel installations than double thread fine tooth screws.
How do domestic and foreign markets differ in screw selection for wooden keels?
Foreign construction markets place a strong emphasis on selecting the correct fastener, using single line coarse tooth screws for wooden keels. In contrast, the domestic market has traditionally relied entirely on double line fine tooth dry wall screws, and transitioning to coarse teeth is a gradual process.
