GB14210 Standard Trumpet Head Black Phosphorus Drywall Screws
Drywall screws are specialized fasteners designed for attaching drywall panels to wooden or metal studs.
• Easy Installation:
Their self-tapping tips and sharp threads allow for quick and smooth insertion, reducing installation time.
• Secure Hold:
The deep threads provide a strong grip in drywall materials, minimizing the risk of panels loosening over time.
• Corrosion Resistance:
Many types are coated (e.g., with zinc or phosphate) to prevent rust, suitable for various environments.
• Accurate Depth Control:
The bugle-shaped head is designed to sink into the drywall slightly without tearing the paper surface, ensuring a smooth finish for painting or plastering.
• Versatility:
Compatible with both wood and metal framing, making them widely used in construction and renovation projects.
