Product Description
The NAS1790-4-8y is a close-tolerance 100° flush-head bolt designed for countersunk structural joints on aircraft airframes. This fastener features a UNJF thread form per NAS specifications, providing high shear strength in critical load-bearing connections. The flush head creates an aerodynamic surface when installed in a 100° countersink, eliminating protrusions that would disrupt airflow.
Commonly used in fuselage skin attachments, wing-to-fuselage joints, and other structural shear applications where a smooth external surface is required. Installation requires proper countersink preparation and torque application per the applicable aircraft maintenance or structural repair manual.
