EPDM Washer

EPDM bonded washers for roofing screws, in 14mm, 16mm and 19mm outside diameter. EPDM is the rubber specified for roof work because it holds up to ultraviolet and ozone where a cheaper elastomer hardens and cracks.

  • M0.8 – M42
  • 2mm – 3000mm
  • Outside diameter 14mm, 16mm and 19mm
  • EPDM — UV and ozone resistant
  • Bonded to a steel or stainless cap
Before you send the enquiry: the head, drive, point, thread form and finish are all specified separately on this item, so almost any combination is possible. Tell us the substrate and the exposure rather than guessing at a part number and we will name the combination.
