Product: 36mm x 0.6mm Fixing Washers for XPS Underfloor Heating Insulation Boards Box Quantity: 20

These high-quality 36mm diameter fixing washers (0.6mm thick) are the ideal mechanical fixings for securing XPS insulation boards (commonly used in underfloor heating installations) to timber subfloors or battens.

• Diameter: 36mm – Provides excellent surface area to distribute load and prevent pull-through on soft insulation materials like XPS foam boards.
• Thickness: 0.6mm – Lightweight yet robust, offering strong holding power without adding unnecessary bulk.
• Material: Typically galvanised or stainless steel (countersunk design for flush fitting).
• Central Hole: ~5-5.5mm – Compatible with standard pozi-drive or woodscrews (e.g., 3.5-5mm diameter, various lengths depending on board/subfloor thickness).
• Pack Size: 20 per box – Perfect for smaller jobs, repairs, or topping up your toolkit without buying in bulk.
