The TTH 35mm Galvanised Washers (Pack of 100) are purpose-built for fixing insulation boards and backer boards securely to timber substrates. Whether you’re installing on walls or floors, these washers provide a professional, no-compromise hold that lasts.
Manufactured from a mix of aluminium and stainless steel, and finished with a protective galvanised coating, they’re ideal for use in areas exposed to moisture — including bathrooms, wet rooms, and kitchens. When paired with appropriate fixing screws, they help anchor boards firmly in place without damaging the surface or compromising the integrity of your installation.
These washers are specifically designed to be used when securing Baseboard to timber structures. For best results, use 12 washers per 1200 x 600mm board, giving you consistent coverage and excellent load distribution across the board.
The 35mm diameter offers a broad contact area, preventing the board from pulling through or cracking during installation. Each washer is smooth-edged for safe handling and manufactured to tight tolerances for a clean, uniform finish every time.
Supplied in handy packs of 100, they’re ideal for both small jobs and larger commercial projects. Whether you’re a tiler, bathroom installer, or general tradesperson, having reliable fixings like these to hand keeps.
