Sirius A4 316 Stainless Steel Spring Washers

The Sirius A4 316 Stainless Steel Spring Washer in M24 is the largest size in this range and is intended for the most demanding heavy-duty fastening applications. The M24 size is used in major structural steelwork, large marine fittings, heavy industrial plant, and civil engineering projects where large-diameter high-strength bolts must be reliably secured against loosening.

Built from A4 grade 316 stainless steel, this washer provides the highest level of corrosion resistance available in stainless spring washers, standing up to saltwater immersion, aggressive chemicals, and extreme outdoor exposure without degradation. The split-ring spring profile delivers substantial clamping force, maintaining fastener integrity under high vibration, shock loads, and significant thermal movement.
