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. (AN3H-15) 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. "C" stands for stainless. Others are cadmium plated.

15% discount on qty of 50-99

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.

My order was sent out quickly and correctly!

Why is it I never get asked to review a back order or items out of stock with no date available in the future. But as to the order for the AN3 bolts, they were great!

Bolts were ordered last minute before going to a Fly-in. I expected them when I got back, but they arrived before I left! Great job!

Easy ordering - I found what I needed quickly and easily, and the information about the bolts (and other products) was clear and understandable. Shipping was fast and accurate. Been dealing with Aircraft Spruce for 5 or 6 years now and I have consistently had great results. My only suggestion for improvement is to add reviews, whether written or in a video, of some of the products that home builders might not be familiar with. You could easily include links to the EAA Hints for Homebuilders instead of making your own - that would be great!

Q&A

Q: How do I add the H after the AN for an AN3 bolt with a drilled head while ordering on-line?

The chart online only offers the bolts with drilled or undrilled shank in both stainless and cadmium. If you wish to order drilled head, you will need to either use the "AN Bolt Selector" which can be foundby searching that phrase on our site, or using the "Order By Part Number" link near the "Cart" icon on each page.

Q: Which nut do I order for AN3-4A?

AN3 bolts use AN365-1032A (Cad Plated) or AN365C-1032 (Stainless) for locknuts and AN310-3 for castle nuts.

Q: Are the stainless bolts (AN3C) the same tensile strength as the cad plated ones?

The tech data sheet does not list a separate tensile strength for corrosion-resistant steel bolts. That would indicate they would be rated the same per the TDS.

Q: What are the quantities for price breaks and the standard package quantities? I know you'll send any quantity, but I'd order above the price breaks and in multiples of the package quantities if they were listed.

The discount schedule for large quantities are: 50-100 = 15% / 100+ = 20%. Package quantities are usually 25 but we can sort them however you prefer as long as you mention it in special instructions at checkout.

Q: Can you offer the CofC for AN3 bolts?

Yes, material certs can be provided. They must be requested at the time of checkout in the shopping cart. Additional fees may apply.
