Tile Backer Board Fixing Washers – Secure & Reliable Board Installation

These tile backer board fixing washers provide a simple, secure, and durable way to attach insulation or tile backer boards to floors and walls. Designed specifically for building and tiling applications, they ensure a flush, stable surface ready for adhesive and tile installation.

Key Features

• Flush Finish Design – Countersunk to allow the screw head to pull in smoothly while keeping the outer rim level with the board surface. Creates a perfectly flat base for adhesive or tile application.
• Perforated Surface for Better Adhesion – The perforated pattern lets adhesives and plasters bond through the washer to the board, reducing the risk of delamination or surface damage.
• Durable Stainless Steel Construction – Corrosion-resistant material ensures long-lasting performance, even in wet or humid environments.
