This pack of 50 19mm EPDM bonded washers is intended for use with self-drilling fasteners, commonly applied in roofing and cladding installations. The washers feature a steel backing and an EPDM rubber layer, which combine to form a seal at points where fixings penetrate sheet materials.
On site, these washers are typically chosen when fixing metal sheeting or panels to timber or steel frameworks. Their use helps limit the risk of water ingress and provides a consistent seal on roofing, wall panels, or canopy structures exposed to the elements.
