Why should you use BS EN 4848 - Pan head screws for aerospace applications?
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.
