Drywall screws are a specialized type of woodworking fastener designed for securely installing gypsum board, lightweight partition walls, and ceiling ceilings. They are equipped with self-tapping characteristics, enabling them to be efficiently secured to wooden or light steel keels without the need for pre-drilling, thus saving valuable construction time.
One of the key features of drywall screws is their distinctive horn-shaped design, which facilitates the later application of putty to achieve a smooth and aesthetically pleasing wall surface. Additionally, the surface of these screws is often treated with rust prevention measures, such as black phosphating or blue-white zinc coating, to effectively prevent rusting within the gypsum board.

Thread Design:
- Single thread coarse teeth for wooden keels - wide threads for fast penetration and reduced wood damage
- Double thread fine teeth for metal keels - fine threads provide strong biting force and minimize metal damage
Diversity of Specifications:
- Available lengths: 25mm for single-layer gypsum board, 35mm for double-layer/multi-layer, up to 50mm for thicker materials
- Typical diameter around 3.5 millimeters, varying based on construction requirements
Special Function:
Some drywall nails feature a tooth-shaped structure that facilitates automatic digging and sinking of holes during installation on hard materials like cement boards or Etter boards. This ensures that the nail cap is securely sunk to a depth of 0.5-1mm on the board surface, preventing any loosening or rusting issues.
Compared to regular self-tapping screws, drywall nails prioritize quick installation and surface flatness of gypsum boards over wood biting strength. Their economic practicality and high efficiency have made them a preferred choice for home decoration, commercial partitions, and other similar applications.

| Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request. | The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements. | The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation. |
