Re: KR> Prop bolts and nuts
If you post this question in corvaircraft someone will come back with more info on this. I went in halfs with someone to get some Belleville washers "https://en.m.wikipedia.org/wiki/Belleville_washer " they are cone shape spring washers. Someone said that there are ut and bolts to go along with them.

Re: KR> Prop bolts and nuts
You'll actually find it both methods (Metal Self Locking Nuts, and Castilated nuts) on certificated aircraft engines with wood props without drive lugs. Both methods are acceptable as far as the FAA is concerned. Saber Manufacturing also makes (undrilled shank) prop bolts that are a higher strength bolt that many builders use. However, they only make 3/8", 7/16", and 1/2" bolts. These bolts have a longer threaded area on the shank, so can be used on varying thicknesses of props without changing bolts. Many of the guys with certificated engines are using these bolts even though they are not necessarily FAA Approved. -Jeff Scott Cherokee Village, AR Sent: Friday, September 28, 2018 at 4:53 PM From: "Rob Schmitt via KRnet" To: 'KRnet' Cc: robert7...@aol.com Subject: Re: KR> Prop bolts and nuts Pete, I am using just regular AN bolts with castle nuts - safety wired.

I have always used all-steel lock nuts, AN 363, to be exact. https://www.aircraftspruce.com/catalog/hapages/an363.php?recfer=11209 That and AN bolts, as you said. Some will advocated regular castle nuts with safety wire, but my approach is that with wooden props, which should be retorqued a few hours after installation, and at least twice a year with the season change, you're less likely to follow through if it involves a half hour of safety wiring.
