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.
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.
Used for the connection between gypsum board and metal keel with a thickness not exceeding 2.3mm, available in black phosphating and yellow zinc coating options. The scope of application and purchase price of both are basically the same. And yellow zinc has a slightly better rust prevention effect, and the natural color of the product is light, which is not easy to fade after coating decoration.
Black phosphating provides a certain level of lubricity and a slightly faster attack speed when entering steel plates. In contrast, blue and white zinc coatings offer a slightly better rust prevention effect and a lighter natural color that holds up well under coating decoration.
No, there is almost no difference in rust prevention capability between blue-white zinc and yellow zinc. The selection is typically determined by user preferences or specific regional usage habits.
Single thread coarse tooth drywall screws feature wider threads and achieve faster attack speeds. Because they do not damage the structural integrity of the wood itself upon entry, they are far more suitable for wooden keel installations than double thread fine tooth options.
These screws are suitable for connecting gypsum boards to metal keels with a maximum thickness of 2.3mm, providing a secure and durable attachment.
For connections under 2.3mm thickness, you can choose between black phosphating and yellow zinc coatings. Both options are priced similarly and share a similar scope of application, with yellow zinc offering slightly better rust prevention and resistance to fading.
