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.

These are great. I am building a small scale radial engine. Will be using a 32-14 prop, and these are the prop bolts. They are perfect. Mike Brainerd

The bolts that came with my kit were slightly bent so they caused a bushing to warp. The new bolts were perfect!

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.

Q: AN Bolt Selector Do you carry close tolerance bolts? How are they designated? I need AN3 close tolerance bolts with a 1 grip length. Thanks.

A close tolerance version with a 1 grip would be AN173-13.
