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.

Although the bolts came from three different places, in 3 different shipments, they all arrived on time and were all correct. Whatever system you used to pull that off seems to be working.. Thanks,

The grip and thread length needed was unusual and not available locally. There were plastic sleeves protecting the threads during shipment, nice touch. The bolts fit perfectly!

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: How do I order AN4 bolts with the head drilled on line?

Use the AN Bolt Selector page. Keyword search "AN Bolt Selector" on our website and click the first result, then use the drop down selections on the page to choose the bolts you need.
