M3 Curved Washer, 304 Stainless Steel - CUWA2M3

The Metric Curved Washer, 304 Stainless Steel is available in 4 sizes (M3 to M6) and is a washer with a curved profile. It sits against a curved or angled surface or applies spring pressure under a fastener.

The range runs to 4 variants, covering sizes M3 to M6. Each variant is supplied in packs of 100.

Made from 304 (A2) stainless steel, a standard austenitic grade with good everyday corrosion resistance. It is a sound choice away from the coast; in chloride-exposed settings, step up to 316 (A4). Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

In wet conditions, keep stainless steel apart from aluminium and galvanised steel with a washer or sleeve, to reduce the risk of galvanic corrosion.
