Need Prop Bolts

[Wayne]

I need a set of prop bolts for my A65. It is not the tapered flange. Specs would help also if no one has any they want to sell.

Re: Need Prop Bolts

Wayne,

When I needed prop bolts I could not find any, as they were no longer available. That was after calling quite a few places. My A&P recommended I call Avico in Miami, FL. I had to give them the size I wanted, (they may be able to help you with that part), and they were a lot cheaper than what you find in the catalogs. You may speak with a female or two that have a hard time understanding English but ask for Greg or Nick. The number is 800-741-6486. Good Luck.

I may have an extra set but I doubt it. You can use the correct length AN bolt with a drilled head as well. They will be $5 ea instead of $25 ea.

Thanks for the info Marty and Mike. Mike do you know the correct AN bolt?

Thanks for the info Marty and Mike. Mike do you know the correct AN bolt?

It will take some very careful measurements of the exising prop bolts, and then possibly some trial and error. Standard AN bolts have a longer grip (the grip is the non-threaded area) and therefore a shorter threaded area than true prop bolts. What works for one prop will likely not work for another, unless they are the same type prop.

For a given prop, there is probably only one length of AN bolt that is right, and since they come in 1/8" increments, it is easy to be off by a size or two. If they are too long, you might bottom out the nut on the grip (you run out of threads). If they are too short, you might not have enough thread showing past the nut. So you could reach your proper torque value, but not know that the nut has bottomed out on the threads. Washer thickness must be factored in, and if you have a skull cap type spinner that is mounted via the prop bolts, its bracket might mean that two of your bolts will need to be longer than the others.

You should be able to get the bolts for about $2 each from Aircraft Spruce, but the problem is knowing exactly which size to order.

Hey Mike, I just noticed you are in Washington. I'm in Norman, and keep my plane at O44 in Slaughterville, not too far from you. Do you ever make it to The Paul's Valley fly-in?

Re: Need Prop Bolts

What prop are you trying to mount? What kind of spinner? I may have the bolts you need, but they are new, AN 6 bolts, not AN76 prop bolts.

Re: Need Prop Bolts

Buy a few of sets in different lengths. Spruce will take back what you don't use.

Re: Need Prop Bolts

Thanks for the info guys. Mt prop is a McCauley but I don't have the model here now. The spinner is just the skull cap type.

Re: Need Prop Bolts

If you have the prop model number there is a good chance that Univair will have the prop bolts. I bought a set from them a year ago for a project. If you know what prop bolt set you need Preferred Airparts might have them at a lower cost. Tom

I have not lately. I usually don't go if i have nothing to fly. I have seen you buzz our strip a time or two in your Piet. I am on Paradise.....if you can call it that.

At least you don't have to worry about crush with a metal propeller. that will make using AN bolts MUCH easier.

Re: Need Prop Bolts

A McCauley 1A90 or 1B90 on a flanged shaft with a skullcap uses AN6H-31A bolts. Use AN960-616 washers on the 4 without the skull cap bracket and AN960-616L on the other 2.

Re: Need Prop Bolts

Thanks John and everyone. I will get them on order tomorrow.

Mike, we are having a fly-in on February 10th at O44 (McCaslin) if you would like to come. Show up around 10AM, and we'll have lunch around noon. There should be a good number of people there if the weather is good, last time we had near 30 planes. Anybody else who is interested is also welcome.
