Sirius A4 316 Stainless Steel Spring Washers

The Sirius A4 316 Stainless Steel Spring Washers are engineered for demanding applications where corrosion resistance and reliable fastening performance are essential. Manufactured from A4 grade 316 stainless steel, these spring washers provide superior protection against rust, oxidisation, and chemical attack — making them an excellent choice for marine, coastal, food processing, chemical, and outdoor environments.

The split-ring design creates a spring action that applies constant pressure to fastener assemblies, effectively resisting loosening caused by vibration, thermal cycling, and dynamic loads. Whether used in light fabrication or heavy-duty industrial installations, these washers deliver consistent, long-lasting performance.

Available in sizes from M3 to M24, there is a suitable option for a wide range of bolted joint applications.
