The AN526-1032R14 is an Aeronautical Standard (AN) aircraft truss head machine screw used in general aviation airframe and interior assemblies. It belongs to the AN526 series, which specifies non-structural Phillips truss-head screws designed for reliable fastening with good load distribution and vibration resistance.

This specific variant is typically:

Thread: #10-32 UNF (fine thread)
Length: 7/8 inch (0.875")
Head: truss head (wide bearing surface, low profile)
Drive: Phillips cross recess
Material: cadmium-plated steel (corrosion resistant aircraft hardware)
It is used in aircraft interior panels, brackets, access covers, avionics installations, and light sheet-metal structures, where a longer #10 fastener is required.

Key features include:

AN (Aeronautical Standard) aviation fastener
Truss head for maximum load distribution
#10-32 UNF thread
7/8" length (longer than R8 variant)
Corrosion-protected steel construction
Designed for vibration resistance in aircraft environments
Common in FAA-certified maintenance and OEM production
