Product Information

Large-diameter metal sheet screws with drill tips prevent rust, leaks, and seepage. The special drill tip allows drilling and fastening to steel purlins (3.2 mm thick) without the need for a pilot hole. The special “Shank Guard” teeth help remove the dullness of the roofing sheet, preventing shingles from scratching the screw’s coating during installation, potentially leading to rust.
