AN4DD30 Airframe Bolt

The AN4DD30 Airframe Bolt features Anodized Aluminum Alloy and has a 1/4-28 thread with a 1/4” shank diameter. All sizes of AN4DD 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 AN4DD30 Airframe Bolt is tapered, to allow easier starting of the nut. The AN4DD30 Airframe Bolt is tapered on the last threads, for ease of installation of the nut. The AN4DD30 Airframe Bolt has a tensile strength of 62,000 psi. If the AN4DD AN4DD30 Airframe Bolt is overstressed, it will bend first rather than snapping.
