Hi, I just got my wooden prop back from Sensenich following a refinishing and rebalancing ($210 plus shipping), and it looks brand new again. My question is, does anyone know the size bolts and nuts off hand? I decided after 10 yrs to replace them, and am struggling to find the exact size and length in the plans. Does anyone remember where those specs are?

I didn't expect to be able to answer this one but I realized that I have a spare prop about 6 feet away from where I'm sitting.  My bolts are .375" diameter by 4.75" long, not counting the bolt head.

I found it!

It's an AN6-45A bolt, MS21045-6S steel split lock nut and two AN960-616 Cadmium steel washers
