✔️ Stainless 1/4 inch fastener with 1 1/8 inch rubber backing
This quarter inch stainless washer pair ships with two matching builders fasteners ready for immediate roof patching. You will typically mount these corrosion resisting plates on metal roofs, asphalt shingles, or siding panels during exterior building upgrades and commercial framing jobs. ✅ Quarter inch diameter hole fits standard fasteners perfectly
✅ 1 1/8 inch outer diameter spreads load across wider surface area
✅ EPDM rubber seal blocks moisture from entering drilled holes
✅ Cold rolled stainless steel resists rust and bending forces
💡 What prevents capillary water wicking through fastener holes in metal panel roofs? This fused backing setup is handy because it locks out humidity before it touches structural framing. - Pressurized EPDM seals expand under bolt tension to block liquid travel along screw threads. - Austenitic steel alloy preserves tensile strength through repeated freeze thaw cycles. - Wide bearing cups distribute point loads evenly so thin sheet metal stays flat and secure.
