Product Description

The AN531-4R8 is a steel tapping screw with a flat countersunk head and Phillips cross-recess drive. This 0.50-inch aeronautical standard fastener secures thin sheet-metal structures and interior panels to airframe components. The countersunk head sits flush with the surface, maintaining smooth aerodynamic contours.

Installation requires matching pre-drilled holes with proper countersink depth per aircraft maintenance manual specifications. Widely used in general and commercial aviation for interior trim, access panels, and non-structural sheet-metal attachments.
