MS21047-08 - Nut

Part number MS21047-08 is a military-standard anchor nut (nutplate) designed to provide a permanent, self-retained threaded attachment point for aerospace and structural assemblies. The component features a fixed threaded barrel mounted to a two-lug plate configuration, allowing rivet installation onto panels or structures where backside access is limited.

This low-profile nutplate is commonly used in aircraft skins, access panels, avionics mounts, and equipment enclosures where repeated assembly and disassembly are required. The threaded insert provides secure machine screw retention while the dual mounting ears ensure stable attachment to the parent structure.
