PROVA Wide-Head Washers are purpose-engineered to lock XPS foam backer boards securely in place without crushing the surface — delivering the stable, flush substrate that professional tile installations demand. When paired with PROVA Fasteners screws (sold separately), they form a corrosion-resistant, watertight fastening system for full peace of mind.

  • Wide-Head Design – 1-1/4″(3.2 cm) head distributes load evenly to prevent pull-through and maintain rigidity under heavy tile or stone.
  • Flush Finish – Low-profile washers sit flat with the board surface for a smooth, tile-ready substrate.
  • Corrosion-Resistant Construction – Rust resistant aluminum alloy steel to provide lasting protection in wet areas.
  • Engineered for XPS Foam Boards – Designed specifically for PROVA Board Plus+; won’t crush or damage the foam core.
  • Waterproof System Compatibility – When sealed with PROVA-Seal, penetrations remain watertight and warranty-approved.
  • Installer-Focused Performance – Purpose-built washers simplify installation and deliver professional-grade strength and reliability.
  • Warranty Approved – Ensures lifetime warranty coverage for your PROVA Board Plus+ Installation.
