About this item
- Stainless steel: Made from high‑grade stainless steel, our 35 mm washers offer superior anti‑corrosion and anti‑wear performance for UK damp climates. The countersunk design lets the screw head sit flush while the outer rim distributes pressure evenly – preventing cracks on tile backer boards and insulation boards.
- 6‑hole perforated: Each washer has six precision holes that allow adhesive or mortar to bond directly through the perforations, eliminating surface delamination and bulging while saving 40% installation time. The grooved centre and convex back grip securely into the board for a slip‑free fix.
- Seamless application: When fastened with the included countersunk screws, the slim profile stays nearly flush with the board. Perforations let plaster or tile adhesive pass through and stick to the substrate, dramatically reducing delamination – ideal for wetrooms, kitchen floors, and tiled surfaces.
- Wide compatibility: These 35 mm washers work on foam boards (XPS/EPS), cement backer units, plasterboard, wooden subfloors, concrete and thermopanels. Perfect for DIYers, builders, and tradesmen fixing insulation boards, underfloor heating, or bathroom tiling across the UK.
- 200 pcs value pack (washers + screws): You get 200 stainless steel fixing washers (35 mm, 6‑hole) plus 200 matching countersunk self‑tapping screws – ready to use out of the box. Ideal for residential renovations, schools, hotels, and apartment builds. No extra purchase needed.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
