The 50-013-5 stud is an aviation-grade fastening component commonly identified as a quarter-turn or turnbutton-style stud used in aircraft assemblies. It is designed to provide quick-attach and secure mechanical fastening in airframe panels, access covers, and structural mounting applications where vibration resistance and rapid installation/removal are required.

This part is associated with helicopter and aircraft OEM applications (including Bell and Agusta configurations) and is typically used in conjunction with mating receptacles or locking mechanisms that allow controlled engagement and disengagement under operational loads.

Key features include:

Aviation quarter-turn / turnbutton-style stud fastener
Precision-machined aerospace-grade hardware
Used for secure panel, cover, and structural attachment
Allows quick installation and removal without full unthreading
Designed for high vibration and cyclic load environments
Manufactured from high-strength alloy steel (variant dependent)
Compatible with aircraft and helicopter airframe assemblies (OEM-specific use)
Corrosion-resistant aviation hardware finish (depending on spec)
Suitable for maintenance access panels and structural fastening systems
Used in certified aerospace maintenance and assembly procedures
