The S4213-14 is an aircraft clip nut (also known as a nut plate / nut clip) used in airframe structures to provide a captive threaded fastening point. It is designed to be installed on sheet metal or structural panels where repeated assembly and disassembly is required without accessing the backside of the structure.

This part is commonly found in Cessna/Textron aircraft assemblies and is part of a broader S4213-series family of airframe hardware where each suffix defines size, grip range, and thread configuration.

Key features include:

Aircraft-grade clip nut (captive nut hardware)
Used in airframe sheet metal assemblies
Allows one-sided installation access (blind fastening)
Typically rivet-mounted to structure
Provides reusable threaded insert for screws/bolts
Vibration-resistant fastening design
Common in Cessna/Textron aircraft structures
Standard aviation maintenance and repair hardware
Corrosion-resistant steel construction (variant dependent)
Interchangeable within S4213-series only if IPC matches
