Where to buy a MS20074-05-06 bolt?
 

While switching over to a Plane-Power
alternator I noticed they supplied some nice
5/16", course thread, drilled head bolts that were new
to me. The part number is MS20074-05-06.
I searched Aircraft Spruce and some others and had no luck.
I would like to find a source for them in 1/4" for other places
on my engine, if available.

Can anyone tell me if this is a newer part number
for an existing type of bolt and also, where to buy them.

Thanks for any info,
Tom

I found the MS20074-05-06 bolts available at:

GAHco
www.gen-aircraft-hardware.com

They are a replacement for the obsolete:
AN75A6

Answering my own question,
Tom

Just a many year later update for those searching the archives...

Spruce does now carry these bolts...
