1" x 1-7/8" x 12G Flat Round Washer, 304 Stainless Steel - FRWA21X178

The Imperial Flat Round Washer (Standard), 304 Stainless Steel is available in 40 sizes (1/8" x 5/16" x 22G to 1" x 2-1/2" x 10G) and is a flat ring that spreads the clamping load of a nut or bolt head and protects the surface being fixed.

This listing has 40 variants covering sizes 1/8" x 5/16" x 22G to 1" x 2-1/2" x 10G. Variants are supplied in packs of 25 to 200, depending on size.

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.

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: Imperial Flat Round Washer (Standard) - 316 Stainless Steel.
