The 65 x 4.2mm Fine Thread Drywall Screws in black phosphate finish are tailored for precision drywall fixing into metal studs. Their fine thread delivers a tight grip and smooth drive, ensuring a strong hold with minimal resistance in high-density substrates. With a sharp piercing point, they’re designed to penetrate quickly without the need for pre-drilling, reducing installation time while maintaining accuracy. The black phosphate coating adds corrosion resistance and enhances performance under power tools. Supplied in a pack of 500, these screws are ideal for smaller jobs, patching, or detailed installations where consistency and quality matter.
