The NAS514P832-8 is a National Aerospace Standard (NAS) aircraft machine screw used in high-reliability airframe and equipment installations. It is part of the NAS514 series, which defines precision pan head Phillips machine screws designed for structural and semi-structural aircraft applications where consistent strength, vibration resistance, and controlled clamp load are required.

This specific variant is typically a #8-32 UNF threaded, 1/2-inch length screw with a Phillips recess pan head and cadmium-plated alloy steel construction for corrosion resistance and durability in aerospace environments.

Key features include:

NAS (National Aerospace Standard) aircraft fastener
Thread: #8-32 UNF fine thread
Length: 0.500 in (1/2")
Pan head with Phillips drive
High-strength alloy steel construction (typically 8740/4037 class steel)
Cadmium plated for corrosion protection (QQ-P-416 type finish)
Designed for aircraft airframe and equipment mounting
High tensile strength (often ~125,000 psi range)
Used in aerospace, avionics, and structural interior assemblies
Precision tolerance for vibration and fatigue resistance
