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.

Q&A
Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.
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.
AN3 bolts use AN365-1032A (Cad Plated) or AN365C-1032 (Stainless) for locknuts and AN310-3 for castle nuts.
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.
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.
Yes, material certs can be provided. They must be requested at the time of checkout in the shopping cart. Additional fees may apply.
A close tolerance version with a 1 grip would be AN173-13.
