What is BS EN 2139 - Flat heat-resisting steel washers for aerospace applications about?
BS EN 2139 is a European Standard series that covers flat heat-resisting steel washers for aerospace applications, enabling the protection of surfaces from damage during installation.
BS EN 2139 specifies the characteristics of flat heat-resisting steel washers for use in aerospace
applications, at temperatures below 650 °C.
Steel washers in BS EN 2139 are intended for use primarily underneath nuts, for use underneath bolt heads the compatibility shall be checked.
Who is BS EN 2139 - Flat heat-resisting steel washers for aerospace applications for?
BS EN 2139 on flat heat-resisting steel washers for aerospace applications is useful for:
- Manufacturers and suppliers of steel washers
- Manufacturers of aerospace equipment and components
- Quality assurance services
- Product design engineers
- Aeronautical engineers
- Regulatory bodies
Why should you use BS EN 2139 - Flat heat-resisting steel washers for aerospace applications?
Surfaces are stressed by fasteners without washers, resulting in cracks and deformities. Steel washers safeguard against such damage by equally dispersing the load and reducing the tension on the fastener. They also prevent the screw from loosening in case of vibrations.
BS EN 2139 provides you guidance on required characteristics for steel washers, including configuration, dimensions, tolerances, surface roughness, material, and surface treatment, enabling you to standardize the dimensional and physical properties of washers for aerospace applications.
By adopting BS EN 2139, you can develop and assess heat-resisting steel washers, enabling protection against damage by distributing and lessening the stress from the fastener by evenly distributing the load.
