Overview
|
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. "C" represents Type 431 Stainless Steel (contains iron which is magnetic). 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.
Note: Drilled bolts listed above are drilled shank only. To order drilled head only or both drilled head and shank bolts, please use our AN Bolt Selector by clicking the link below. Click here for the AN Bolt Selector |

Quality bolts Back ordered on original shipment - took a week + to receive if time sensitive
Came with a hex head on one end and threads on the other, it is a fine 1/2 bolt. Flawless same-day shipping by ACS made this bolt better than AN bolts you can buy elsewhere.
When I need an aircraft bolt quick and for a good price, Aircraft Spruce is where I get it. I like that they ship it with a fixed shipping cost and not as need to be determined like some others. Ive been unpleasantly surprised by that a few times.
Fast delivery. Good product.
