The Pipistrel 5011072 is an M4 aerospace-grade hex self-locking nut used in light aircraft structural and system assemblies where a vibration-resistant threaded fastening is required.

It features a self-locking mechanism (typically nylon insert or all-metal deformed thread design depending on specification variant) that prevents loosening under continuous vibration and operational loads. This makes it suitable for use in composite airframes and lightweight aircraft structures, such as those produced by Pipistrel.

The nut is commonly installed in airframe brackets, avionics mounting points, interior fittings, and secondary structural connections, where secure fastening and low maintenance requirements are important.
