We recommend using #8 or #10 stainless steel or corrosion-resistant truss-head or pan-head screws that are at least 1-1/4 inches long (or long enough to penetrate framing studs by at least 3/4 inch). The wide, flat underside of a truss-head or pan-head screw distributes weight evenly across the nail flange without biting into or pulling through the vinyl. Avoid using countersunk (flat-head) screws, as their tapered undersides wedge into the flange slots and restrict the panel’s ability to expand and contract naturally. Always drive screws through the center of the pre-punched slots, leaving approximately a 1/16-inch gap between the screw head and the flange.
