Thanks very much JG3 but I need 6 so will try and get them all the same - for the prop.

Aircraft Propellers and Spares Moorabbin will have them.

Yes - I have got lots of different AN bolts from them. Will order if not in stock.

 

Cheers,

And you'll pay US wholesale + freight + Australian suppliers markup + GST + postage to your place.

This is one of the many reasons I prefer to fly European (metric) aircraft - most "fixings" of the appropriate standard, can be acquired through any half decent nuts & bots supplier.

You can get that size & standard from other suppliers.

BUT

not to aircraft specifications.

I use " Lee,s Brothers " at the nuthouse Parramatta. Seem to have anything l need

That certification ticket is MONEY IN THE BANK to aircraft specialist suppliers.

I have minimal experience in this area, however when I need to replace a metric bolt/nut/screw/washers, of a known standard (ie one already fitted to aircraft) I can find the identical fixing at my local specialist (not aviation) nuts & bolts retailer. The fixing suppled do not just look like the original , they are exactly the same, tensile strength, diameter, length (overall & thread) and thread pitch. The only change I have made is to use upgraded lock nuts in critical area (I am not a fan of the ubiquitous "Nylock" in these areas).

 

To me, (a simple sole with limited brain capacity) American sourced aircraft/parts are a nightmare of multiple measurement types  & systems - why anyone wants to hang on to imperial (US or UK) measuring systems is a level of lunacy that can not be explained by any logical process.

I can't understand why we continue to depend on imperial measurements in aircraft when everything else is metric. Why Jabiru use AN when Australia is metric I don't know other than they export quite a few engines to the US. Even the US went metric but some President I believe declared in unamerican & it never progressed. Everything is expressed in fractions as well. Pain in the proverbial. Anyway I have purchased unusual length AN bolts from Hawker Pacific so you could give them a try.

Why did we have to go with the French metric !. When Germany ( din ) and Japan were metric, way before degaul  got a bee in his bonnet, against England !.

Just because it says 8.8 on the head may not guarantee that much nowadays. The wrong grade of Chinesium could have been used. With AN hardware one can be reasonably sure you are getting what you paid more for.

News to me - I dont care what metric system is used as long as it's intuitive, linear and constant  - basically everything the imperial system(s) are not.

Happy to give them a try but no good without the details. Who are they?

Tex - Are you sure you have the nomenclature precisely correct? The information below seems to indicate the correct nomenclature is AN5H-26 or AN5H-26A, depending on whether you need a drilled shank or not.

 

AN5H-26 is a 5/16" x 24tpi bolt with 2-5/16" grip length, with a drilled head, and a drilled shank.  AN5H-26A is a 5/16" x 24tpi bolt with 2-5/16" grip length, with a drilled head, and an undrilled shank.

AN bolts are different to all other "standard" hardware, and are measured by grip length, and have shorter threads than standard fasteners.

 

Standard SAE fasteners are measured by overall shank length, measured from the underside of the head. In addition, standard SAE fasteners can have a discrepancy in thread diameter, depending on which company made them.

 

Another Australian supplier that may be able to supply, is Australian Aerospace Engineering. Here is a link to their catalogue.

Yes that is correct, the first place I contacted told me it would be a AN5H-26A. None one listed had them in stock.
