Under-Cutting Drywall Screws are specifically designed for fastening drywall boards and cementitious panels to mild steel structural framing and partition systems in professional drylining applications. Engineered with a self-drilling point and specialised bugle head with an undercutting ring, these screws provide fast penetration into steel framing while creating a clean flush finish without damaging the board surface. The undercutting ring design helps improve countersinking performance and reduces surface breakout, making them ideal for achieving high-quality finishes in demanding drywall installations.

Manufactured from hardened SAE C1020 steel and available with high-performance EvoShield® corrosion-resistant coating, these screws deliver reliable long-term durability and strong holding performance in interior construction environments. Their efficient drill point geometry helps reduce installation time and eliminates the need for pre-drilling into mild steel framing systems, improving productivity on site.

Under-Cutting Drywall Screws are widely used in partition walls, suspended ceilings, steel stud framing, commercial fit-outs, office interiors, residential developments, and general drylining applications where secure board fixing, smooth countersinking, and professional finishing quality are essential.
