BS EN 4509 is a European Standard that discusses components used in the aerospace industry. The purpose of BS EN 4509 is to provide the best industry design requirements for 100° countersunk normal head screws to ensure strength and corrosion resistance in aerospace applications.
BS EN 4509 specifies the characteristics of screws, 100° countersunk normal head, offset cruciform recess, threaded to head, in titanium alloy, anodized, with aluminium pigmented coating, metric series.
BS EN 4509 provides guidance on classification for normal screw heads, including minimum tensile strength of 1100 MPa and maximum operating temperature of 315 °C.
BS EN 4509 on 100° countersunk normal head screws for use in aerospace is useful for:
Screws are the most prevalent threaded fastening mechanism used on planes. They differ from bolts in that they are often constructed of weaker materials. When it comes to the manufacturing and use of aerospace components, reliability, consistent performance, and durability are crucial.
BS EN 4509 provides users guidance on required characteristics for normal head screws for aerospace applications, including configuration, dimensions, mass, tolerance of form, position, materials, and surface treatments, enabling users to standardize the physical and dimensional properties of normal screws.
BS EN 4509 creates a standardized approach for manufacturers of 100° countersunk normal head screws ensuring quality, dependability and compatibility with existing codes.
By adopting BS EN 4509, you can develop and assess 100° countersunk normal head screws to ensure strength, performance and durability in aerospace applications.
