Designed for exterior use, this screw provides strong, reliable fixing into metal with corrosion-resistant coating for long-lasting performance outdoors. Buildex® Sheet Metal Screws are designed for fixing light-gauge metal, ducting, and trims to steel or timber. Sharp-cutting threads provide quick bite and strong clamp force, while corrosion-resistant finishes ensure long-lasting performance across multiple head styles.
