PALNUT (P/N 11378) - New Surplus

The 11378 is a stamped steel palnut designed to resist fastener loosening under vibration. This thin locknut installs against a standard nut or directly on a stud, creating a secondary locking action through spring tension and friction. Spring steel construction provides reliable performance in aircraft structural assemblies, bracket installations, and high-vibration environments.

The palnut's compact profile allows it to function as a jam nut in confined spaces where traditional locking methods are impractical. Installation follows standard aerospace practices per AC 43.13-1B guidance.
