NUT (P/N ms20364-428) - New Surplus

The MS20364-428 is a thin self-locking hex nut designed for aircraft fastening applications. This prevailing-torque nut resists loosening under vibration without requiring cotter pins or safety wire. Manufactured to Military Standard MS20364 specifications, it's commonly cross-referenced as AN364-428 and assigned NSN 5310-00-595-7475.

Used in airframe shear-loaded joints where vibration retention is critical. Installation follows aircraft maintenance manual torque guidance. Replace the nut if the locking element no longer resists finger-turning, indicating wear of the prevailing-torque feature.
