Sirius A4 316 Penny Repair Washers Stainless Steel

The Sirius A4 316 Penny Repair Washers in Stainless Steel are a dependable fastening solution designed for applications where a broad load-bearing surface and superior corrosion resistance are essential. Manufactured from grade A4 316 stainless steel, these washers offer excellent protection against rust, salt spray, and chemical exposure, making them well-suited to marine, coastal, and outdoor environments.

Penny washers — sometimes called repair washers — feature a notably large outside diameter relative to their bore, allowing them to spread clamping loads effectively across softer or damaged materials. This makes them ideal for roofing repairs, cladding fixings, timber connections, and general maintenance tasks where a standard washer would not provide sufficient bearing area.

Available in a range of sizes, with internal diameters from 5mm to 12mm and outside diameters from 25mm to 35mm, there is a suitable variant for a wide variety of fastener sizes and applications.

Features and Benefits:
• Grade A4 316 stainless steel construction for outstanding corrosion resistance
• Large outside diameter spreads load and prevents pull-through
• Ideal for marine, coastal, outdoor, and wet environments
• Suitable for roofing, cladding, timber, and general repair work
• Compatible with a range of bolt and screw sizes across the variant range
