AN4CH17A Airframe Bolt

The AN4CH17A Airframe Bolt features Corrosion-Resistant Steel and has a 1/4-28 thread with a 1/4” shank diameter. All sizes of AN4CH 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 AN4CH17A Airframe Bolt is tapered, to allow easier starting of the nut. The AN4CH17A Airframe Bolt is tapered on the last threads, for ease of installation of the nut. The AN4CH17A Airframe Bolt has a tensile strength of 125,000 psi. If the AN4CH AN4CH17A Airframe Bolt is overstressed, it will bend first rather than snapping.
