M12 Flat Round Washer, 304 Stainless Steel - FWAA2M12

Made in 304 (A2) stainless steel, the Metric Flat Round Washer is a flat ring that spreads the clamping load of a nut or bolt head and protects the surface being fixed.

This listing has 13 variants covering sizes M2 to M24. Pack quantities depend on size: packs of 50 to 200.

The A2 (304) stainless material suits indoor, fresh water and typical outdoor use. Where the fastening is exposed to salt air, pool chemicals or marine conditions, A4 (316) is the grade to use instead. 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.

Key specifications

Selecting the right option

Match the washer to the fastener size, and check outer diameter and thickness for the load. Washers are listed by the size of bolt they suit. Use stainless washers with stainless bolts to avoid mixed-metal corrosion. Near the coast, around pools or in marine settings, use the A4 (316) version instead: Flat Round Washer DIN125A Stainless Steel.
