Product Description

PRODUCT PARAMETER

Nails

DIN 18182 nails are specialized fasteners designed for secure fixing of gypsum boards, light-gauge steel studs, and other construction materials. These nails feature a bugle head (flat, rounded profile) and sharp, coarse threads for self-tapping into soft materials like gypsum, wood, or thin metal without pre-drilling . Common materials include carbon steel (zinc-plated or black phosphate for corrosion resistance) and stainless steel for high-moisture environments . Sizes range from M3.5 to M5.5 in diameter, with lengths of 13–152 mm, ensuring compatibility with various panel thicknesses . Standards like DIN 18182-2:2019 specify dimensions, thread pitch, and mechanical properties, emphasizing load-bearing capacity and anti-loosening performance .

Applications:

Gypsum Board Installation: Primarily used to secure drywall panels to wooden or metal studs in residential and commercial buildings, ensuring flush finishes and structural integrity .
Lightweight Construction: Fasten metal brackets, ceiling grids, or insulation materials in modular construction systems .
Industrial Fixtures: Secure signage, electrical conduits, or HVAC components in indoor environments requiring quick, tool-friendly installation .
DIY Projects: Ideal for assembling furniture, shelving, or temporary structures where corrosion resistance and ease of use are critical .
Specialized Fixings: High-strength variants (e.g., 8.8-grade steel) are used in heavy-duty applications like securing traffic barriers or machinery mounts .
