NUTPLATE – S3429-1A (Replaces S1860-1A)

Two-lug anchor nutplate used for creating a permanent threaded fastening point in aircraft sheet metal structures. It is installed by riveting to the airframe structure, providing a captive threaded nut that allows repeated assembly and disassembly without damaging the parent material. The design ensures stable load distribution and reliable fastening in vibration-prone aerospace environments.

Application:
Aircraft fuselage and wing sheet metal assemblies, access panels, inspection covers, interior structure fastening points, and general airframe maintenance installations requiring captive threaded inserts

Function:
Provides a permanent threaded attachment point by being riveted to structure, allowing bolts or screws to be installed and removed repeatedly while maintaining secure load transfer and alignment in thin-sheet airframe structures
