About This Product

Features
■A sealing rubber washer with excellent watertightness and long-term corrosion resistance.・Unlike conventional EPDM, this product shuts out metals that tend to be included as components, and has extremely strong insulation properties as well as amazing durability and viscosity.
・We use hot-dip galvanized Z27 iron from a JIS-certified factory to further improve quality than conventional products.

■ApplicationsBondel washers are most commonly used in the construction industry in Japan. In particular, when using drill screws to fasten the exterior walls and roofs (iron plates) of factories and warehouses with drill screws, it is effective in preventing rainwater from entering the screw holes. In addition, new applications are expanding into solar power generation and a variety of other fields.

■MaterialHot dip galvanized steel sheet Z27, stainless steel SUS304

■SizeRepresentative sizes: 12mm, 12.7mm, 16mm

■FeaturesThis is the world's only Bondel washer that was originally developed by KST.The Bondel washer is molded from hot-dip galvanized steel plate and is further coated with strong galvanizing using a special manufacturing method. Since it is plated again after molding, it takes well over 500 hours for red rust to appear in a salt spray test, and the washer cross section (hole surface and outer periphery), where the plating effect tends to fade, is also protected from rust.

■ApplicationsIt is used for temple roofs and coastal properties, and is cheaper than stainless steel. *This product is still new, so we can continue to create new styles by developing new uses. We would like to hear your requests and inquiries.

■StockWe have an inventory supply system in place so that we can deliver the required quantity to our customers in the shortest possible delivery time.
