Drywall screws are essential fasteners meticulously engineered to firmly secure drywall materials like gypsum board and lightweight partition walls. Below, we delve into their unique structural features, classification, specification parameters, and vital usage precautions:
1. Structure and Material Characteristics
1. Appearance Features
Horn Head Design: Crafted in an elegant horn shape, this design amplifies the force area, effectively preventing surface cracks in the board. It ensures a snug, secure fit between the screw and the board.
• Slender Nail Body: Featuring a slender, threaded body, it effortlessly pierces the board, anchoring firmly to the keel or wall for outstanding stability.
2. Materials and Craftsmanship
Material: Typically crafted from robust carbon steel, the surface undergoes phosphating, galvanizing, and similar treatments to significantly boost rust resistance.
• Thread Design: Available in two distinct types - double line fine teeth and single line coarse teeth:
Double Line Fine Thread: With its refined thread design, it’s ideal for securing gypsum board to metal keels (thickness ≤ 0.8mm), providing exceptional fastening strength.
Single Line Coarse Thread: The broader thread is perfect for connecting gypsum board to wooden keels, offering rapid drilling and minimizing damage to the wood structure.
2. Classification and Usage
1. Classification by Thread Type
Double Line Fine Tooth Drywall Nail: Perfect for gypsum board to metal keel connections, it boasts tight threads and an excellent holding effect.
Single Line Coarse Tooth Drywall Nail: Designed for gypsum board to wooden keel applications, it delivers swift penetration and is ideal for wooden materials.
2. Classification by Special Function
Self-Drilling Drywall Nail: Equipped with a drill bit at the tip, it seamlessly combines drilling and tapping, making it perfect for speedy metal keel installations (thickness ≤ 2.3mm).
Pin Screws: Tailored for thin metal plate connections, these screws offer exceptional hardness on the threaded surface, suitable for specific industrial applications.
3. Classification by Material and Surface Treatment
Black Drywall Nails: Primarily used for securing gypsum boards, they are cost-effective and well-suited for typical indoor environments.
Stainless Steel Drywall Nails: With impressive corrosion resistance, they thrive in humid settings like bathrooms and kitchens.
Galvanized Drywall Nails: Offering excellent rust resistance, they are ideal for long-lasting durability in demanding scenarios.
