Product Description

Drywall screws are specialized fasteners meticulously crafted to secure drywall materials, including gypsum board and lightweight partition walls. Below is an in-depth exploration of their unique structural attributes, diverse classification, precise specification parameters, and crucial usage precautions:

1, Structure and Material Characteristics

1. Distinctive Appearance Features

Ingenious Horn Head Design: The head exhibits a horn shape, ingeniously expanding the force area to prevent surface cracking of the board. It ensures a seamless and robust fit with the board.

• Elongated Nail Body: Featuring a slender, threaded body, this design effortlessly penetrates the board and achieves a firm grip to the keel or wall, ensuring stability.

2. Premium Materials and Craftsmanship

Material Excellence: Typically fabricated from high-grade carbon steel and treated with processes like phosphating or galvanizing, these enhancements elevate their rust prevention performance.

• Ingenious Thread Design: Available in two styles—double line fine teeth and single line coarse teeth:

Double Line Fine Thread: This finer thread is perfect for connecting gypsum board to metal keels (thickness ≤ 0.8mm), offering exceptional fastening strength.

Single Line Coarse Thread: With a wider thread, this design excels in connecting gypsum board to wooden keels, providing rapid installation and preserving wood integrity.

2, Classification and Usage

1. Classification by Thread Type

Double Line Fine Tooth Drywall Nail: Designed for gypsum board to metal keel connections, these nails boast tight threads for a superior holding effect.

Single Line Coarse Tooth Drywall Nail: Perfect for gypsum board to wooden keel connections, providing swift application and compatibility with wood materials.

2. Classification by Special Function

Self-Drilling Drywall Nail: Equipped with a front-end drill bit, it facilitates simultaneous drilling and tapping, ideal for quick metal keel installations (thickness ≤ 2.3mm).

Pin Screws: Intended for thin metal plates, these screws offer high hardness on the threaded surface, suitable for targeted industrial applications.

3. Classification by Material and Surface Treatment

Black Drywall Nails: Primarily for gypsum board fixation, these cost-effective nails suit general indoor environments.

Stainless Steel Drywall Nails: Boasting superior corrosion resistance, ideal for damp or high-humidity areas such as bathrooms and kitchens.

Galvanized Drywall Nails: Offering excellent rust resistance, perfect for scenarios demanding long-term durability and reliability.
