The AN526-1032R10 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 defines non-structural Phillips truss-head screws designed to provide good load distribution and vibration resistance in light aircraft applications.

This specific variant is typically:

Thread: #10-32 UNF (fine thread)
Length: 5/8 inch (0.625")
Head: truss head (wide bearing surface)
Drive: Phillips (cross recess)
Material: cadmium-plated steel (corrosion-resistant aviation hardware)
It is widely used in aircraft interior panels, avionics mounting, brackets, access covers, and light sheet-metal fastening, where a #10 fastener with a slightly longer grip length is required.

Key features include:

AN (Aeronautical Standard) aviation fastener
Truss head for improved load distribution
#10-32 UNF thread
5/8" length
Steel construction with corrosion protection
Designed for vibration-prone aircraft environments
Common in FAA-certified maintenance and OEM installations
