BS EN 2414 is a European standard on aerospace series which covers washers, chamfered, with counterbore, in alloy steel, cadmium plated.
BS EN 2414 specifies the characteristics of chamfered washers, with counterbore, in alloy steel, cadmium plated, for maximum operating temperature 235 °C.
BS EN 2414 on chamfered washers is applicable to:
Chamfered washers also known as a Through-Hardened washer are used with high strength friction grip / preloaded bolting assemblies. Designed to stop the bolt head or nut embedding into the material being clamped or deforming when under load instead distributing the force onto the material over a wider area.
Cadmium Electroplating (Nadcap Accredited) Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a "sacrificial coating," corroding before the substrate material.
In manufacturing, it is often desirable to hide the fasteners used in the joining process. One way to do so is to use a counterbore. Chamfered washers are designed to stop the bolt head or nut embedding into the material being clamped or deforming when under load.
BS EN 2414 helps the user by specifying the characteristics of chamfered washers, with counterbore, this can help you increase safety in operations and the production process.
