The AN526-1032R8 is an Aeronautical Standard (AN) aircraft truss head machine screw used in general aviation airframe and interior applications. It is part of the AN526 series, which defines Phillips truss-head screws designed for non-structural aircraft fastening where good load distribution and vibration resistance are required.

This specific variant is typically:

Thread: #10-32 UNF (fine thread)
Length: 1/2 inch (0.500")
Head: truss head (wide bearing surface, low profile)
Drive: Phillips (cross recess)
Material: cadmium-plated steel (corrosion resistant aviation hardware)
It is commonly used in aircraft interior panels, avionics mounting, brackets, access covers, and light sheet-metal structures.

Key features include:

AN (Aeronautical Standard) aviation fastener
Truss head for maximum surface load distribution
#10-32 UNF fine thread
1/2" length
Steel construction with corrosion-resistant plating
Designed for vibration-prone aircraft environments
Common in FAA-certified maintenance and OEM installations
