Solid Finishing Cup Washers M3–M8 — A2 Stainless Screw Cup

Why choose these solid finishing cup washers

Solid finishing cup washers give countersunk screws a clean, professional seat — the cupped profile spreads load around the bore while concealing the fixing hole. Pressed from A2 stainless steel, they keep their bright finish in interior, workshop and light outdoor use, and pair neatly with countersunk machine screws or woodscrews on cabinetry, signage and trim work.

Sizes available

Five common metric bore sizes covering the most-used countersunk fixings: M3, M4, M5, M6 and M8. Each washer accepts a matching countersunk-head screw and centres it automatically as it tightens.

Pack options

Available in packs of 10, 20 or 100 — useful for everything from a one-off repair through to fit-out quantities. Mix sizes in one checkout to qualify for free UK delivery on orders over £20.

Typical uses

Kitchen and wardrobe joinery, handle and knob fixings, signage and panelling, AV and electrical face-plate trims, audio rack screws, marine cabin joinery, boat trim and any countersunk fixing where a stainless seat tidies the appearance.

How to fit

Drill or counterbore so the cup sits flush with the surface, drop the washer into the bore, then drive a matching countersunk screw through it. The cup profile self-centres the screw and creates a finished recess that hides any minor over-drilling. Use with countersunk A2 screws for a colour-matched fixing.
