M5 x 15mm Penny Repair Washers, Pack of 20 – A2 304 Stainless Steel DIN 9021 Form G Wide-Form Mudguard Fender Washer for Wood, Metal, Garden, Automotive & DIY

• A2 304 STAINLESS STEEL – EXCELLENT RUST & CORROSION RESISTANCE Manufactured from A2 304 stainless steel for excellent rust and corrosion resistance across outdoor, indoor, and damp environments. Unlike zinc-plated mild steel washers that rust the moment the coating is scratched, A2 stainless retains its corrosion resistance throughout its service life — ideal for any project where long-term reliability matters more than the lowest possible price.
• DIN 9021 FORM G WIDE-FORM – 15mm OUTER DIAMETER FOR LOAD SPREADING Manufactured to the DIN 9021 standard with a 5.3mm inner bore and 15mm outer diameter — a wide-form "penny" washer (also known as Form G, mudguard, or fender washer). The oversized contact area spreads bolt clamping force across a wide surface, preventing the bolt head from pulling through soft materials like timber, plastic, plasterboard, sheet metal, or composite panels.
• M5 x 15mm – PACK OF 20 A2 STAINLESS STEEL PENNY WASHERS Each pack contains 20 individual M5 x 15mm stainless steel penny washers. The 5.3mm inner bore fits all standard M5 bolts, machine screws, coach bolts, and threaded rod, while the 15mm outer diameter spreads load over a wide area. A practical quantity for general repair, automotive bodywork, garden structures, marine fixings, trailer hardware, and any project requiring wide-surface stainless washers.
• VERSATILE – WOOD, METAL, GARDEN, AUTOMOTIVE & MARINE APPLICATIONS A genuinely multi-purpose washer for fixing soft and thin substrates: car body and panel repair, caravan and motorhome fittings, trailer board fixings, roof rack installations, sun sail and pergola anchors, fence post brackets, garden trellis structures, sheet metal repairs, and any DIY or trade project requiring wide-surface stainless fixings. Suitable for indoor and outdoor use including coastal environments where mild steel would corrode.
• UNIVERSAL M5 FIT – COMPATIBLE WITH ALL STANDARD M5 BOLTS & SCREWS With a precise 5.3mm inner bore, these penny washers are universally compatible with all M5 metric bolts, hex bolts, machine screws, coach bolts, threaded rod, and rivets across all major brands and standards. Pairs perfectly with A2 304 stainless hex bolts, button head socket screws, and dome nuts.
