M6 Flat Round Washer, 316 Stainless Steel - FRWA4M6
The price shown is for the box.
Available
The Inox Standard Flat Round Washer, 316 Stainless Steel is a flat ring that spreads the clamping load of a nut or bolt head and protects the surface being fixed.
The range runs to 12 variants, covering sizes M6 to M36. Pack quantities depend on size: packs of 10 to 100.
A4 (316) stainless steel contains molybdenum (about 2 to 3 per cent), which improves its resistance to chlorides. It is the grade normally chosen for coastal, pool, marine and food-processing settings, and it costs more than A2 (304). Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.
Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. In wet conditions, keep stainless steel apart from aluminium and galvanised steel with a washer or sleeve, to reduce the risk of galvanic corrosion.

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. For indoor and general outdoor use where chlorides are not a concern, the A2 (304) version is the lower-cost option: Inox Standard Flat Round Washer - 304 Stainless Steel.
