Product Description

Drywall screws are specialized fasteners crafted to securely attach drywall materials, such as gypsum boards and lightweight partition walls. Below is a comprehensive overview of their structural attributes, classification objectives, specification details, and usage guidelines:

1, Structure and Material Characteristics

1. Distinctive Appearance Features

Horn Head Design: Crafted in a unique horn shape, the head enhances the contact area, safeguards against surface cracking of the board, and ensures a snug, secure fit with the board.

• Slender Nail Body: The nail's slender, threaded design facilitates easy penetration through the board, ensuring a robust attachment to the keel or wall.

2. Materials and Craftsmanship Excellence

Material: Typically constructed from durable carbon steel, the surface undergoes treatments like phosphating and galvanizing to significantly boost rust resistance.

• Advanced Thread Design: Available in two distinctive styles: double line fine teeth and single line coarse teeth:

Double Line Fine Thread: Characterized by fine threading, ideal for securing gypsum boards to metal keels (thickness ≤ 0.8mm), offering superior fastening strength.

Single Line Coarse Thread: With broader threading, this design is optimal for attaching gypsum boards to wooden keels, providing rapid insertion while minimizing wood structure damage.

2, Classification and Usage

1. Classification by Thread Type

Double Line Fine Tooth Drywall Nail: Perfect for linking gypsum boards with metal keels, featuring tight threading for an exceptional fixing effect.

Single Line Coarse Tooth Drywall Nail: Designed for connecting gypsum boards to wooden keels, offering swift penetration ideal for wood materials.

2. Classification by Special Function

Self-Drilling Drywall Nail: Equipped with a drill bit at the front, this nail allows simultaneous drilling and tapping, ideal for fast installations on metal keels (thickness ≤ 2.3mm).

Pin Screws: Employed to connect thin metal plates, boasting high hardness on the threads, making them 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 perfect for typical indoor environments.

Stainless Steel Drywall Nails: Offering strong resistance to corrosion, these nails are perfect for high-humidity areas like bathrooms and kitchens.

Galvanized Drywall Nails: Featuring excellent rust resistance, these nails are tailored for environments requiring long-lasting durability.
