AN7H20 Airframe Bolt
The AN7H20 Airframe Bolt features Cadmium Plated Steel and has a 7/16-20 thread with a 7/16” shank diameter. All sizes of AN7H bolts have a 0.656 inch thread length, regardless of grip length. This thread length has been carefully calculated to accommodate a full-height nut plus one AN960-716 washer. The threaded end of the AN7H20 Airframe Bolt is tapered, to allow easier starting of the nut. The AN7H20 Airframe Bolt is tapered on the last threads, for ease of installation of the nut. The AN7H20 Airframe Bolt has a tensile strength of 125,000 psi. If the AN7H AN7H20 Airframe Bolt is overstressed, it will bend first rather than snapping.
