{"product_id":"black-penny-washers","title":"Black Penny \/ Mudguard Washers M3–M10 — A2 DIN 9021","description":"\u003ch3\u003eWhy choose these black penny washers\u003c\/h3\u003e\n\u003cp\u003eBlack penny (or mudguard) washers combine the load-spreading benefit of an extra-large outside diameter with the corrosion resistance of A2 stainless steel and a discreet chemical-black finish. Ideal where a standard washer would crush thin sheet, plastic or fabric — the wider face spreads the clamping force evenly, while the black finish ties in with darker hardware and trim.\u003c\/p\u003e\n\u003ch3\u003eSizes available\u003c\/h3\u003e\n\u003cp\u003eStocked in eleven bore-by-OD combinations to DIN 9021: M3, M4, M5, M6, M8 and M10 bores with OD options to suit each diameter — from M3 × 9mm up to M10 × 30mm. Pair with matching A2 hex nuts, dome nuts or button-head screws for a clean black-and-stainless assembly.\u003c\/p\u003e\n\u003ch3\u003ePack options\u003c\/h3\u003e\n\u003cp\u003eAvailable in packs of 10 or 20 per size.
