Product Description
The NAS1581F3T4 is a reduced-head, 100-degree countersunk bolt manufactured from alloy steel per National Aerospace Standard specifications. This fastener provides flush fastening in close-tolerance shear joints where airframe skin meets substructure. The reduced head design minimizes protrusion and aerodynamic disruption in streamlined aircraft assemblies.
Installation requires preparation of countersink cavities to match the bolt's 100-degree cone angle, with fastening torque and grip length specified in aircraft maintenance manuals. Commonly used in fuselage and wing skin attachments on general and commercial aircraft.
