Hex head aircraft bolts are made of high-strength type 4037 or 8740 alloy steel (type 8740 is most commonly used). The bolts are centerless ground and threaded after heat treatment. Minimum tensile strength 125,000 PSI. Cadmium plated per specification QQ-P-416A, Type II, Class 3. Available with shank drilled for cotter pin or undrilled for stop nut application, and with or without drilled head for safety wire. Specify bolts to have undrilled shank by adding letter “A” after the dash number. For bolts with drilled head add letter “H” after the AN number. See illustrated examples. The length of AN aircraft bolts is measured from under the head to the end of the shank. The “grip” is the unthreaded portion of the shank. See table for conversion of length and/or grip to proper AN callout.
