COLLAR,PIN-RIVET,THREADED (P/N hl70-6) - New Surplus

The HL70-6 is a threaded pin-rivet collar designed to clamp aircraft structural joints using a frangible hex mechanism. This fastener features a UNJF-3B internal thread that provides precise, repeatable preload when installed with 3/16-inch Hi-Lok pins. The collar's hex head shears at a predetermined torque value, ensuring consistent clamping force across airframe assemblies.

Installation requires a compatible Hi-Lok driver tool applied until the hex breaks cleanly. Commonly used in primary and secondary structural repairs where controlled preload and vibration resistance are critical.
