Drywall screw is a type of woodworking fastener specifically used for installing gypsum board, lightweight partition walls, and ceiling ceilings. It has self tapping screw characteristics and can be efficiently fixed to wooden or light steel keel without pre drilling to save construction time.

Its iconic design is the horn shaped design, which facilitates the later application of putty to ensure a smooth and beautiful wall surface. The surface is often treated with rust prevention (such as black phosphating or blue white blue zinc coating), which can effectively prevent rusting inside the gypsum board.

• Thread Design: Available in single thread coarse teeth for wooden keels (fast penetration) and double thread fine teeth for metal keels (strong biting force with minimal damage).
• Diversity of Specifications: Common lengths include 25mm for single-layer gypsum board and 35mm for double-layer, with standard diameter of 3.5mm (custom sizes available).
• Special Function: Some models feature a tooth-shaped structure for automatic hole digging when installing hard materials like cement boards, ensuring firm sinking of nail cap (0.5-1mm depth).
• Performance: Optimized for quick installation and surface flatness while maintaining economic practicality for various applications.

Ideal for gypsum board fixation, ceiling structure reinforcement, and lightweight partition wall construction. Also suitable for:

• Door and window frame installation (requires precise measurements)
• Cabinet and furniture assembly (attention to detail recommended)
• Decorative line installation (crown molding, baseboards, etc.)

Always use proper tools and follow manufacturer instructions for secure, lasting installations that enhance both structural integrity and aesthetic appeal.
