Nail Washer

Nail Washers are oversized washers designed to be used with nails or screws for fixing sheets, roofing panels, and cladding. They spread the load over a wider area, preventing sheet damage and pull-through during fastening. Manufactured to ASTM and DIN standards, they are available in flat, domed, or rubber-sealed types. Their large OD and optional sealing liners provide strength and weatherproofing for outdoor applications. They are widely used in roofing, cladding, timber construction, and light structural projects.
