Product Introduction
The Black Phosphate Self-Tapping Drywall Screws are engineered to provide superior performance and durability for securing drywall to wood and metal studs. Designed with various thread and head types, these screws ensure optimal grip and minimal risk of cracking. They are perfect for interior wall and ceiling installations in residential and commercial projects, offering corrosion resistance and efficient application.
Product Advantage
| Feature | Drywall Screws | Drywall Nails |
|---|---|---|
| Holding Power | Superior (threaded grip) | Smooth, may loosen |
| Cracking Risk | Low (bugle head) | Higher (hammering stress) |
| Installation Speed | Fast (power driver) | Fast (nail gun) |
| Corrosion Resistance | Better (coatings available) | Prone to rust |
| Reusability | Hard to remove | Easier to pull out |
The black phosphate coating provides exceptional rust resistance, making the screws ideal for indoor use and ensuring long-term durability.
Thanks to the sharp self-drilling point and bugle head design, these screws can be quickly driven into drywall without the need for pre-drilling, speeding up installation times.
The bugle head design helps reduce the risk of paper tearing on drywall, ensuring a secure and tight fit without damaging the surface.
With different thread types (coarse for wood and fine for metal studs) and sizes, these screws are versatile and suitable for various construction projects, from drywall installation to corner bead attachment.
For areas exposed to moisture, the galvanized and zinc-plated options offer superior corrosion resistance, ensuring longevity even in high-humidity environments.
Product Parameters
Bugle Head: The most common, flat head design that can sink into the surface of gypsum board, making it easy to cover with subsequent batches of plaster.
Pan Head: Less commonly used, usually used in situations that require additional support.
Coarse Thread: Suitable for Wood Studs, with stronger grip.
Fine Thread: Suitable for metal frames (Metal Studs) to prevent wire slippage.
Black Phosphate: rust proof, suitable for indoor use.
Galvanized: corrosion-resistant, suitable for humid environments.
| Parameter | Options / Specifications | Remarks |
|---|---|---|
| Material | Carbon steel, Stainless steel (rare) | Most are carbon steel with coating for rust resistance. |
| Surface Treatment | Black phosphate, Zinc-plated, Galvanized | Black phosphate for indoor use; galvanized for moisture-prone areas. |
| Head Type | Bugle head (most common), Pan head | Bugle head prevents paper tearing on drywall. |
| Drive Type | Phillips (#2), Pozidriv, Square (Robertson) | Phillips is the most widely used. |
| Thread Type | Coarse (for wood), Fine (for metal studs) | Coarse: Better grip in wood; Fine: Less likely to strip metal. |
| Point Type | Sharp self-drilling point | No pre-drilling needed for wood/metal studs. |
| Shank Type | Partially threaded (common), Fully threaded | Partial threading reduces cracking risk. |
| Diameter (Gauge) | #6 (3.5mm), #8 (4.2mm) | #6 for standard drywall; #8 for heavy-duty. |
| Length | 1" (25mm), 1-1/4" (32mm), 1-5/8" (41mm), 2" (50mm) | Longer screws for thicker materials. |
| Packaging | Bulk boxes (1lb, 5lb, 25lb), Pre-counted (100/200/500 pcs) | Contractors prefer bulk packagin |
For Wood Studs → Coarse thread (#6 or #8) + 1-1/4" to 1-5/8" length.
For Metal Studs → Fine thread (#6) + 1" to 1-1/4" length.
High Humidity Areas → Zinc-plated or galvanized screws.
Fire-Rated Walls → Check local codes (sometimes longer screws are required).
Product Applications
Used for securely attaching drywall to wood or metal studs in residential and commercial buildings.
Drywall screws are commonly used to attach corner beads, ensuring straight, clean corners.
Perfect for repairing holes in existing drywall or supporting joint compound and tape in damaged areas.
Drywall screws can be used in smaller construction projects to secure subflooring materials to floor joists.
While not the primary choice, drywall screws can also be used for securing trim and molding in non-structural applications.
FAQ
A: Coarse-thread screws are best for wood studs as they provide a stronger grip. Fine-thread screws are designed for metal studs and are less likely to strip metal.
A: For single-layer drywall, 1-1/4" (32mm) is recommended. For double-layer drywall, use 1-5/8" to 2" (41mm–50mm). For metal studs, 1" to 1-1/4" (25mm–32mm) screws work best.
A: Drywall screws are not recommended for outdoor use as they are not corrosion-resistant enough. For outdoor projects, use deck screws instead.
A: Drywall screws are not designed for reuse, as they can strip easily when removed and lose their holding power.
