Product Description

The MS21045-5 is a self-locking hex nut with all-metal prevailing-torque design built to Military Standard MS21045. Manufactured from steel with 5/16-24 UNJF threads, this nut maintains secure fastening under vibration and thermal cycling common in aircraft service. The prevailing-torque mechanism resists loosening without deforming the bolt or stud, making it ideal for airframe brackets, engine mounts, and structural assemblies.

Install on 5/16-24 bolts or studs, ensuring proper thread engagement and applying torque per the applicable aircraft maintenance manual.
