The MS24693-C50 is a military standard aerospace machine screw used in aircraft structures where a flush, aerodynamic surface is required. It belongs to the MS24693 (AN507 equivalent) series, which defines 100° countersunk Phillips machine screws used in both structural and non-structural aircraft assemblies.

This specific dash number is typically:

Thread: #8-32 UNF
Length: 1/2 inch (0.500")
Head: 100° countersunk flat head (flush mount)
Drive: Phillips cross recess
Material: corrosion-resistant steel (often cadmium plated or passivated)
It is commonly used in aircraft skin panels, fairings, access covers, and equipment mounting points where surface smoothness and vibration resistance are important.

Key features include:

Military Standard: MS24693 (AN507 equivalent)
Flush countersunk 100° head for aerodynamic surfaces
#8-32 UNF fine thread
Steel construction with corrosion-resistant finish
Used in aircraft airframe and interior assemblies
High strength and fatigue resistance for aviation use
Common in FAA-certified maintenance and OEM production
