Product Description
The MS21045-7 is a self-locking hex nut designed for 7/16-20 UNF threaded bolts in vibration-prone aircraft assemblies. This steel nut features a prevailing-torque locking mechanism that resists loosening under cyclic vibration and dynamic loads common in airframe and engine-adjacent installations. Qualified to MS21045/NASM21045 aerospace standards, it maintains fastener integrity without additional safety wire or lock washers.
Maximum service temperature is 450°F. Install per aircraft maintenance manual torque specifications, noting that prevailing-torque nuts have limited reuse capability and should be replaced if removed.
