Product Description
The 333-1246-000 is a #4-40 UNC self-locking steel nut designed to prevent fastener loosening under vibration. The nylon insert creates friction that maintains clamp load in aircraft assemblies and avionics equipment. Suitable for machine screws in equipment brackets and rack fasteners.
Installation requires at least one thread protruding beyond the nut per FAA AC 43.13-1B guidance. Avoid use in rotating joints where the self-locking feature could create binding.
