It is the most cost-effective screw for indoor drywall installation.
Key Features：
✅ Black Phosphate Coating – Rust and corrosion resistant, suitable for dry indoor environments.
✅ Self-Tapping Design – Self-tapping thread, quickly penetrates gypsum board and metal/wood keels.
✅ Bugle Head – Flat round countersunk head design, flatly embedded in the surface, easy to plaster.
✅ #6 Diameter, 1-1/4 Inch Length – Standard size, suitable for single-layer gypsum board.
✅ Economical – High cost performance, suitable for home decoration and commercial projects.
Common Specifications Of Black Plasterboard Screws
1/ 2 Drywall Screws
1/2 Drywall Screws (13MM Drywall Screws) are short-size drywall screws designed for thin gypsum boards and special scenarios. They are suitable for thin gypsum boards (1/4 inch or 3/8 inch thick). They ensure that they penetrate the board surface and embed 5-8 mm into the keel or substrate to avoid excessive penetration and damage to the back structure
1 -1 /2 Inch Drywall Screws
1-1/2 inch plasterboard screws (38mm plasterboard screws) are designed for thin and light boards and precision construction scenes. After penetrating the board, they are only embedded in the wooden keel or metal frame by 3-5 mm, while maintaining 7-10 pounds of pull-out force to ensure the effective bite strength of the thread, especially suitable for scenes that are sensitive to depth, such as suspended ceilings and partitions.
2 Inch Drywall Screws
2 Drywall screws (50MM Drywall Screws) are the most perfect size in the decoration field.Balance of depth and strength: 2-inch length can penetrate the standard 12.7mm gypsum board and fully embed into the wood structure or metal keel, ensuring that the thread engagement depth is more than 15mm, avoiding the risk of loosening due to being too short or penetration caused by being too long.

Advantages of Black Drywall Screw
Rust and corrosion prevention:
The phosphate layer can isolate oxygen from moisture and slow down the oxidation of screws. It is suitable for dry indoor environments such as bedrooms, living rooms and offices
Reduced friction: The microporous structure on the surface absorbs lubricating oil and reduces the resistance when screwing in, especially suitable for high-density gypsum board or hardwood keel.
Enhanced adhesion:
The phosphate layer provides a rough base surface for subsequent coatings (such as touch-up paint) to enhance the bonding strength (if painting is required).
Beautiful and hidden:
The black matte texture is close to the color of the gypsum board joint putty, which reduces the color difference after repair and improves the finished beauty.
Avoid reflection:
The black matte surface can avoid reflection during installation, and black is easier to identify
Applicable Scenarios Of Black Plasterboard Screws
Dry indoor environment: residential partitions, ceilings, wooden frame gypsum board fixings.
Low-cost projects: 20%-30% lower than galvanized screws, suitable for budget-sensitive projects.

- Home Renovation DIY
Why Choose Black Drywall Screws?
- Best value for money: lower cost than galvanized screws, suitable for dry environment projects with limited budget.
- Perfect match for drywall: compared with ordinary screws, the phosphate layer reduces the friction of screwing in and protects the integrity of the drywall.
- Concealment advantage: the black surface reduces the traces of repairs after painting.
