TIMCO Multi-Purpose Screw 3.5 50mm black PH drywall

high-performance drywall screw specifically engineered for securing plasterboard to timber studwork. These screws feature a sharp needle point that allows for immediate surface penetration without the need for a pilot hole, ensuring a quick start and reducing the risk of wood splitting. The body is finished with a black phosphate coating, which serves two critical purposes: it provides essential corrosion resistance against the moisture often found in wet plaster and prevents chemical reactions with the gypsum that could lead to unsightly “bleeding” through the finished paintwork.

Designed with a bugle head, the screw is capable of sinking smoothly into the drywall surface without tearing the protective paper face, creating a flush finish that is easy to mud and sand. The coarse thread pattern is optimized for a powerful grip within soft timber, offering significantly higher pull-out resistance than fine-threaded alternatives. These screws are typically driven using a PH2 bit, which provides a secure engagement that minimizes cam-out and allows for high-speed installation in both professional and DIY interior construction projects.
