PALNUT (P/N b330-13) - New Surplus

The B330-13 is a spring-steel palnut lock nut designed to prevent fastener loosening under vibration. This stamped fastener cross-references to MS27151-13 aerospace standards and serves as a jam nut on threaded bolts and screws in aircraft assemblies. Commonly used on Robinson R22 helicopter components, the palnut installs directly onto the primary fastener and tightens to create a locking action.

Installation requires verification against your aircraft's Illustrated Parts Catalog and adherence to Robinson maintenance manual specifications for proper torque and compatibility.
