Drywall Screws

Product  introduction

Drywall screws are self-tapping fasteners specifically designed for installing lightweight panels such as gypsum board and fiberboard. Made from carbon steel or stainless steel, they feature a unique structural design for efficient installation. Their heads are typically countersunk (flat) or bugle-shaped, with surfaces treated by galvanization, phosphating, or other rust-resistant processes. The deep, coarse threads and pointed tip allow them to penetrate panels quickly without pre-drilling, ensuring a tight bite that prevents gypsum board from cracking.

Galvanized carbon steel drywall screws are suitable for dry indoor environments, providing sufficient rust resistance for conventional decoration needs. Stainless steel drywall screws (e.g., 304 stainless steel) offer superior corrosion resistance, making them ideal for humid scenarios like kitchens and bathrooms. Common specifications range from M2.5 to M4.2 in diameter and 16-50mm in length, compatible with 6-12mm thick gypsum boards, and comply with national standards such as GB/T 3098.5 (Mechanical Properties of Fasteners – Self-Tapping Screws). With advantages like high-efficiency installation and precise positioning, they are widely used in ceiling grid fixation, partition board connection, and interior decoration projects, serving as core fasteners in modern lightweight wall systems for construction and renovation.
