BS EN 4848 is a standard that covers pan head screws for aerospace applications, to ensure structural integrity and vibration resistance in aerospace operations.
BS EN 4848 specifies the characteristics of externally threaded fasteners, pan head, Spiral Drive Recess, coarse tolerance normal shank, medium length thread, in titanium alloy, anodized, MoS2 lubricated, for aerospace applications.
BS EN 4848 specifies the classification for pan head screws depending on the minimum tensile strength of 1100 MPa and maximum operating temperature of 315 °C.
BS EN 4848 on pan head screws for aerospace applications applies to:
Pan head screws are a type of non-countersunk screw head that is commonly used in self-tapping, self-drilling and machine screws. They have a recessed socket, wide heads, a flat bearing surface, high vertical or curved sides, and a flat or slightly domed top surface.
BS EN 4848 provides users guidance on required characteristics for pan head screws, including configuration, dimensions, tolerances, masses, materials and surface treatment, enabling users to standardize the dimensional and physical properties of pan head screws.
BS EN 4848 provides users guidance on dimensions for pan head screws based on thread code, length code, mass and designation to ensure compatibility with aerospace systems and installations.
With obedience and compliance to BS EN 4848, users can develop and assess pan head screws to ensure a firm hold, vibration resistance and stability in aerospace applications.
