Product Description
The MS21042L3 is an all-metal self-locking hex nut with an integral extended washer for load distribution. Manufactured to MS21042 aerospace standard, this nut features a prevailing-torque mechanism that prevents loosening under vibration and thermal cycling common in aircraft service. The extended washer spreads clamping loads across structural surfaces, reducing stress concentration.
Used to secure structural brackets, fittings, and assemblies in airframe construction. Install with matching machine screws per aircraft maintenance manual specifications, observing proper torque values and reuse limitations for self-locking fasteners.
