Sirius A4 316 Stainless Steel Spring Washers

The Sirius A4 316 Stainless Steel Spring Washer in M8 is a popular medium-duty size used extensively in engineering, marine, and construction applications. The M8 size provides greater spring force and load capacity than smaller variants, making it a reliable choice for securing bolts in pipework systems, structural fixings, vehicle bodywork, and outdoor installations.

Constructed from A4 grade 316 stainless steel, these washers offer proven resistance to corrosion, salt spray, and a wide range of chemicals, ensuring long service life in exposed or demanding conditions. The split-ring design generates firm spring tension that holds M8 fasteners securely in place, even where vibration or cyclical loading is a concern.
