NUT LKG (P/N gyn186n) - New Surplus

The gyn186n is a self-locking nut designed to maintain preload in vibration-prone aircraft assemblies. This prevailing-torque locking nut resists loosening during flight operations and ground handling. Commonly used on flight-control linkages, control surface hinges, and structural fastener applications where vibration could compromise joint integrity.

Install and torque per aircraft maintenance manual specifications, following applicable MS or NAS standards for the joint diameter and load requirements. The self-locking feature eliminates the need for additional safety wire or secondary locking devices.
