AN4C67A Airframe Bolt

The AN4C67A Airframe Bolt features Corrosion-Resistant Steel and has a 1/4-28 thread with a 1/4” shank diameter. All sizes of AN4C bolts have a 0.469 inch thread length, regardless of grip length. This thread length has been carefully calculated to accommodate a full-height nut plus one AN960-416 washer. The threaded end of the AN4C67A Airframe Bolt is tapered, to allow easier starting of the nut. The AN4C67A Airframe Bolt is tapered on the last threads, for ease of installation of the nut. The AN4C67A Airframe Bolt has a tensile strength of 125,000 psi. If the AN4C AN4C67A Airframe Bolt is overstressed, it will bend first rather than snapping.
