- Looking for reliable roofing fasteners for your metal roofing project?
Rubber washer roofing nails - also called corrugated nails, umbrella roof nails, or twisted shank roof nails - do one job: keep a roof sealed through years of sun, rain, and wind. The galvanized shank holds off rust on exposed surfaces, and the rubber washer under the head does the part that matters - it compresses to close the hole so water can't track back under the sheet.
They're a staple line for hardware wholesalers, roofing contractors, and building-material distributors, and they seat straight into corrugated metal sheets, iron roof tiles, and cement boards. We supply them in bulk and under your own brand (OEM packing), and quote by shank type and coating.
