Details
- High-quality materials: Made of iron and galvanized
These butterfly-shaped washers are sturdy, firm and not easily deformed.
They are the highest quality four-pronged washers you can find on the market.
They are durable, anti-wear and anti-corrosion.
Enjoy reliability and quality with these fixing washers.
- Seamless application: When fixed with the appropriate steel screws, our perforated thin metal washer adheres firmly to the surface
The perforation of the fixing disc allows the adhesive or plaster to stick to the surface of the board, minimizing the risk of delamination or surface damage.
Used for insulation boards, tile backer boards, gypsum boards, composite boards, extruded sheets, backing boards on a tiled floor or simply for fixing building boards to frames.
- Easy-to-use washers: These heavy-duty fixing washers are a must-have for installing tile boards
These fixing discs have been specially designed to provide an easy and secure way to help fix backing boards and insulation boards to the floor and walls of the most common materials (wood, concrete, thermoplastic boards and synthetic insulation materials).
- Package contents: each pack of 200 easy to fix heavy duty steel washers, which measure 28 mm in diameter, and generally 8 washers per board are required, although this depends on the size of your backing board.
