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.

Reviews

Since the expansion of Aircraft Spruce the customer service seems to be in a bit of hurry to get me off the phone. You can tell a change. The goal is to make the customer warm and fuzzy when the order is placed. Aircraft Spruce is still is a number four in my opinion. Good job. C.R.H.

The bolts from Aircraft Spruce have always been fantastic and are the only ones used on my plane. And thats why Im using them as axles for another heavy duty project, I need reliability and durability under load.

I ordered two bolts and I got one with a cotter pin hole and the other with out a cotter pin hole. I had to eat the cost.

Im not sure what I can say other than theyre high quality, AN spec bolts. ACS is the perfect vendor with fast shipping, great customer service, great stuff and competitively priced making buying bolts a pleasant experience. Im not sure what else can be asked for.
