The AN526-832R7 is an Aeronautical Standard (AN) aircraft truss head machine screw used in general aviation airframe and interior installations. It belongs to the AN526 series, which defines non-structural truss-head Phillips screws designed for good load distribution and vibration resistance in light aircraft assemblies.

This specific variant is typically:

Thread: #8-32 UNF (fine thread)
Length: 7/16 inch (0.437")
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, brackets, access covers, avionics mounting, and light sheet-metal structures, where a slightly shorter #8 fastener is required.

Key features include:

AN (Aeronautical Standard) aviation fastener
Truss head for load spreading and reduced pull-through
#8-32 UNF thread
7/16" length
Steel construction with corrosion protection
Designed for vibration resistance in aircraft environments
Common in FAA-certified maintenance and OEM installations
