1000PCS 35mm Insulation Metal Washers, Galvanised Iron Easy Fix Washers with Six Holes for Insulation Boards, Plasterboard, Tile Backer Board and Gypsum Boards

• 【Galvanised Iron Construction】These 35mm washers are made from galvanised iron. The metal material stays firm under pressure, helping your insulation board or tile backer board remain securely in place over time.
• 【Six-Hole Design for Adhesive Flow】Each easy fix washer features six holes. This perforated pattern allows adhesive or plaster to pass through and bond directly to the board surface. You get a stronger finished layer with less risk of surface delamination.
• 【1000 Pieces for Larger Projects】This pack provides 1000 pcs of 35mm diameter washers. Enough quantity for fixing insulation boards, tile backer boards, plasterboards, or other construction boards. No need to reorder frequently – keep your work moving without interruption.
• 【Multi-Surface Application】Suitable for insulation boards, tile backer boards, gypsum boards, extruded plates, composite boards, and fixing building boards to timber or metal frames. Works on floors and walls in various construction settings.
• 【Penny Washer Style – Wider Coverage】The 35mm diameter gives these washers a penny washer profile, distributing load over a larger area. This helps prevent board damage around the screw head, especially with softer insulation materials.

html Secure insulation and tile backer boards with confidence – 1000 pcs 35mm galvanised iron easy fix washers. Fixing insulation boards or tile backer boards to floors and walls requires reliable fasteners. These 35mm metal washers are designed to hold firmly while allowing adhesives to do their job. What you get: - 1000 pcs insulation metal washers - Diameter: 35mm (1.38 inches) - Six-hole design for adhesive penetration - Material: Galvanised iron - Centre hole fits standard screws (5.5-6mm recommended) Why choose these easy fix washers? The galvanised iron construction provides consistent performance. Each washer maintains its shape under load, distributing pressure evenly across the board surface. The six-hole pattern keeps maximum board surface exposed – adhesives and plasters reach the board directly, helping the finished layer stay attached without weak spots. Installation made simple: Use steel screws of appropriate size. Drive through the centre hole into the substrate. The six holes let adhesive or plaster flow through, creating a mechanical bond between the finishing layer and the board. This design minimises the risk of surface separation. Applications include: - Insulation boards (thermoboard, PIR, phenolic) - Tile backer boards (Marmox, Wedi type) - Plasterboards and gypsum boards - Extruded polystyrene (XPS) boards - Composite boards - Fixing wire mesh or construction boards to timber or metal frames Value for larger work: With 1000 pieces in one pack, you have enough washers for substantial projects – from room renovations to new builds. Save time on reordering and keep your materials consistent. Note: Screws not included. Select screw length based on your board thickness and substrate material.
