What is BS EN 2648 – Concave washers about?
BS EN 2648 is a European standard on aerospace series which covers washers, concave, in alloy steel, cadmium plated.
BS EN 2648 specifies the characteristics of concave washers, in alloy steel, cadmium plated, maximum operating temperature 235 °C.
They are intended to be used with nuts to EN 2647.
Who is BS EN 2648 – Concave washers for?
BS EN 2648 on concave washers is useful for: 
- Manufacturers of aerospace equipment and components
- Concave washer manufacturers
Why should you use BS EN 2648 – Concave washers?
A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer).
Concave spherical washers, also known as dished washers, are the female or bottom washer in a spherical washer assembly.
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.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 2648 walks you through the characteristics of concave washers, in alloy steel, cadmium plated, maximum operating temperature 235 °C. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
