M12 x 40mm White Nylon Penny Washers, Pack of 10 – DIN 9021 Form G Wide-Form Plastic Insulating Fender Mudguard Washer for Electrical, Insulation, Automotive & DIY

• HIGH GRADE NYLON (POLYAMIDE) – NON-CONDUCTIVE, LIGHTWEIGHT & CORROSION PROOF Manufactured from high-quality nylon (polyamide PA6) — electrically non-conductive, naturally non-magnetic, and completely immune to rust or corrosion. Ideal for any application where metal washers would conduct electricity, transfer heat, scratch a painted surface, or cause galvanic corrosion when in contact with dissimilar metals. Lightweight, easy to cut if needed, and chemically resistant to oils, fuels, and most solvents.
• DIN 9021 FORM G WIDE-FORM – LARGE 40mm OUTER DIAMETER FOR LOAD SPREADING Manufactured to the DIN 9021 standard with a 13.0mm inner bore and 40mm outer diameter — a wide-form "penny" washer (also called 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, plywood, plastic, panel board, or sheet metal — and protecting paint and delicate surfaces from damage during tightening.
• M12 x 40mm – PACK OF 10 WHITE NYLON PENNY WASHERS Each pack contains 10 individual M12 nylon penny washers with 13.0mm inner bore, 40mm outer diameter, and 3.0mm thickness. Suitable for electrical isolation between metal parts, automotive bodywork repair, caravan and motorhome installations, vibration dampening, protecting paintwork during tightening, plumbing, and any project requiring lightweight non-conductive load-spreading washers.
• ELECTRICAL ISOLATION & GALVANIC CORROSION PREVENTION A key advantage over metal washers — nylon prevents electrical conductivity between metal bolt and metal substrate, essential for electrical earthing isolation, panel insulation, and instrument enclosures. Equally valuable for preventing galvanic corrosion when fixing dissimilar metals together (e.g. aluminium panels to steel chassis), where direct metal-to-metal contact would create accelerated corrosion at the joint over time.
• UNIVERSAL M12 FIT – COMPATIBLE WITH ALL STANDARD M12 BOLTS & SCREWS With a precise 13.0mm inner bore, these nylon penny washers are universally compatible with all M12 metric bolts, machine screws, coach bolts, threaded rod, and wood screws across all major brands and standards. Pairs perfectly with stainless steel, brass, or plated steel hex bolts and machine screws. Available across a full range of sizes from M3 through M12 in 10-pack and 20-pack quantities — browse our store for the complete nylon penny washer range.
