Product Description
The NAS517-4-14 is a close-tolerance flat countersunk head machine screw with a 100° head profile and UNF threads. Manufactured from steel, this fastener provides flush panel fastening in aircraft structural assemblies where a smooth aerodynamic surface is critical. The countersunk design allows the screw head to sit flush with the surrounding material, eliminating protrusions that could disrupt airflow or create snag points.
Installation requires verification of length and grip specifications against the aircraft's Illustrated Parts Catalog and compliance with NAS517 standards. Commonly used in fuselage skin attachment, control surface fastening, and interior panel applications.
