AN5 Bolts
|
 |
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.
