HL13VF6-4 - Hi-Lok

Hi-Lok aerospace fastener pin with flush countersunk head, designed for high-strength structural fastening in aircraft and aerospace assemblies. The fastener features a precision close-tolerance shank and externally threaded end for installation with a compatible Hi-Lok collar, providing controlled preload and vibration-resistant retention. The flush-head configuration allows installation in countersunk holes for smooth aerodynamic surfaces and reduced protrusion in airframe structures.
