Black Flat Washers Form A M3–M10 — A2 Stainless DIN 125

Why choose these black Form A flat washers

Form A flat washers are the standard general-purpose washer for most metric bolted joints — a wider face than the bolt head spreads load and protects the joint surface. Pressed from A2 stainless steel and chemically blackened, these washers give you full corrosion resistance with a discreet matte finish that disappears against black hardware and dark trim.

Sizes available

Stocked across seven common metric bores to DIN 125: M3, M4, M5, M6, M7, M8 and M10. Pair with matching A2 black hex nuts, dome nuts or button-head screws for a fully colour-co-ordinated assembly.

Pack options

Available in packs of 10 or 20 per size. Mix sizes in one checkout to qualify for free UK delivery on orders over £20.

Typical uses

Cabinet and furniture making, audio and AV equipment, computer chassis and 19-inch rack work, motorcycle and bicycle fittings, signage, dark architectural metalwork, and any black-themed installation where a bright washer would clash with the finish.

How to fit

Place the washer under the nut or bolt head with the flat face against the workpiece. Form A is the standard medium-thickness washer — use a heavier Form B/C only where extra load spread is required. A light residual oil from manufacture can be wiped off with a clean cloth before final assembly.
