Product Description
The MS21045-9 is a self-locking hexagon nut conforming to MS21045/NASM21045 aerospace standards. Steel construction with an all-metal prevailing-torque locking feature provides vibration resistance in high-stress applications. UNJF-3B 9/16-18 thread specification enables secure fastening on airframe structural attachments and critical assemblies.
Installation requires adherence to aircraft maintenance manual torque values, accounting for prevailing torque resistance. Observe reuse limits during assembly—self-locking nuts have finite reusability cycles before replacement is required.
