AN4-14 Airframe Bolt

The AN4-14 Airframe Bolt has a 1/4-28 with a 1/4” shank diameter. All sizes of AN4 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 AN4-14 Airframe Bolt is tapered, to allow easier starting of the nut. The AN4-14 Airframe Bolt is tapered on the last threads, for ease of installation of the nut. The AN4-14 Airframe Bolt has a tensile strength of 125,000 psi and a shear strength of 76,000 psi. If the AN4 AN4-14 Airframe Bolt is overstressed, it will bend first rather than snapping.
