Product Description
The MS21042-25 is an all-metal self-locking hex nut conforming to MS/NASM21042 specifications. This reduced-height, reduced-hex steel nut provides prevailing-torque retention through metal deformation rather than polymer inserts, making it suitable for elevated-temperature aerospace applications. The nut secures panels, brackets, and structural assemblies where vibration resistance is critical.
Installation requires matching the correct dash-number thread size and following torque specifications per aircraft maintenance manuals and standard practices.
