Product Description
The HLT428-6-7 is a Hi-Lok threaded pin with a protruding shear head, designed for aerospace-grade structural fastening. This aerospace-grade alloy steel pin installs with a frangible collar to create controlled preload in high-shear airframe joints. The collar fractures at a precise torque value, ensuring consistent clamp-up without over-tightening.
Used in primary and secondary airframe structures where reliable load transfer and fatigue resistance are critical. Installation requires matching the specified collar to the grip code per OEM structural repair manual (SRM) and aircraft maintenance manual (AMM) specifications.
