Product Description
The NAS517-4-1 is a 100-degree flush head machine screw with cross-recess drive and close-tolerance specifications. Manufactured from alloy steel with 1/4-28 UNF threads and 0.531-inch length, this screw is designed for shear joints in aerospace assemblies. The countersunk profile seats flush with airframe skin and panel surfaces, eliminating protrusions that would disrupt aerodynamic flow.
Commonly installed in fuselage skin attachments, wing panels, and access covers where flush fastening is critical. Installation requires adherence to NAS517 specifications and aircraft maintenance manual torque values to ensure proper countersink depth and clamp load.
