...and probably zinc coated.The bolts corroded badly in the sockets.
Anyone out there know a supplier of long AN bolts for a Prince propeller.Unfortunately the bolts supplied were not of a standard we were happy with .The bolts we require are AN8H-53A.Seems very hard to source.Thanks.Ron.
probably had nothing then!Mike your knowledge would probably lead me to a distributer of big AN bolts.Can you help please?

..Prop Bolts" sometimes have a shorter thread area....
^^^^^^^^^^^^^^^^^longer
I have 5 good (+ one with buggered threads) 1/2" x I'd say -56 bolts, w/drilled head and more than 1.25" of thread. Believe they are Sabers though, head marking is somewhat like an F911
I looked on the website, "stockmarket.aero"... It appears that Airfasco (you can Google them - they make a lot of the AN hardware for major suppliers but will sell to individuals) has 316 of them.

The thread section on the one is actually bent, like someone left it hanging holding everything. The other 5 are clean, zero corrosion and all roll true and a glass plate. I bought them years ago off Ebay as stock..Hi Irishfield ,Thanks for your reply which we find interesting that one bolt has a damaged thread.Most of mine have damaged threads after withdrawing the rusted bolts from the lugs.One bolt actually broke of internally.The head marking is the same,I believe Sabers.My engineer suspects the threads are not rolled like the AN bolts.Would you agree?As to why the bolts rusted in the lugs we cannot fathom.Manufacturer says we installed them wet or we used thread lock.Certainly none of the above.As aircraft is always hangared in the driest environment in NZ we are at a loss to explain.Hence my reason to use AN bolts.Your thoughts?
Another source for AN hardware.

Their website mentions Airfasco distributor.
If all else fails and you are unable to get bolts with a hole in the head and you don't want to drill the hole, safety washers such as these would do the job.
