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. Click here for the AN Bolt Selector |
These bolts were exactly what I needed to replace my rust damaged prop bolts. I could not source them in the UK and received them within 72hrs of ordering. Fabulous service Thank you.
BOLT UNDRILLED AN7-36A
Prop bolts for my airboat.
Aircraft Spruce is always a constant, and reliable source for what I need. Products are always of good quality. Shipping, well, I’m sure Aircraft Spruce has little latitude in that area.
Cadmium bolts.... they work as theyre supposed to.
Was able to pick the bolts I needed, showed up perfect!
These are the prettiest AN6H-6A Bolts I have ever seen.
You kept shipping costs down. Great!
excellent
Cant beat real AN hardware. Very well packaged from Aircraft Spruce. I use these type bolts on race cars to eliminate failures, never lets me down.
the only thing I would change is a faster shipping method .

The max is .374", and min .371"
AN7 bolts have 7/16-20 threads, so the nut would also have to have the same thread size. Please refer to the aircraft parts manual for the style of nut Cessna recommends for this application.
It depends on the application, but both .032 and .041 will fit through the hole.
Per the Tech Data Sheet, the hole location is determined from the start of the threads, on the head side, to the center of the drilled hole. AN3 = 17/64", AN4 = 5/16", AN5 = 23/64", AN6 = 7/16", AN7 = 31/64", AN8 = 39/64".
Stainless bolts are corrosion resistant for applications where corrosion is a problem. CAD plated bolts are made of steel with CAD plating to help surface corrosion, but it can been worn or chipped off.
The nominal length is the length from under the head to the end of the shank.
We do offer all of the types shown, but unfortunately not in every size. For example, drilled head is not available in AN4-3 stainless, but is available in AN5-4 cadmium.
It is drilled for 1/16" cotter pin so it will be slightly larger than 1/16".

The grip length is the unthreaded portion on the bolt.
