Product Description
M6 A2 Stainless Steel Bonded Roof Sealing Washers
These M6 bonded roof sealing washers combine an A2 stainless steel outer washer with an EPDM rubber backing. Designed for use with M6 fixings, they have a 16mm outside diameter and help seal around fixing holes in roofing sheets, cladding and external panels.
The stainless steel washer spreads the clamping load, while the rubber backing compresses against the panel surface to help prevent water ingress. EPDM offers resistance to weathering and ozone, making it well suited to outdoor sealing applications.
Key Features
- M6 fixing size: for use with compatible 6mm bolts and fixings.
- 16mm outside diameter: provides coverage around the fixing hole.
- A2 stainless steel: corrosion-resistant metal backing for general outdoor use.
- Bonded EPDM rubber: compresses to help seal against the mating surface.
- Roofing and cladding applications: suitable where a sealed fixing point is required.
