OK, you guys may not believe in loctite but I do!! OP, take your choice, try it to see if you like it. Loctite is not glue. It comes in various strenghts denoted by it's color. Blue is what you would use here and for general assembly use. Yes, be aware if retorqueing a wood prop you must overcome the loctite to snug it some more. Not a big deal and neither is "it's hard to change props", it's not if you are using the correct tools, box wrench-YES, a big pair of pliers-NO! Make that HELL NO!!! Ditto to NO VICE GRIPS! Correct size box wrench or socket, 6 point or 12 point are good. Only a small amount is required, one drop per nut. The same amount of torque is required to loosen a loctited assembly as when it was tightened, then the left over loctite acts sorta like a nylock nut and requires a tool to continue to spin it off, not just your fingers. It's EZ to clean off if you decide you don't like it and want to discontinue use on that application. Just clean off the male threads with a small hand wire brush. I have 35 years experence building successful racing engines and race cars, and now model airplanes and have learned how and when to use loctite. The parts didn't fall off my race cars, and they don't fall off my planes if I don't get lazy and forget to use loctite ( 2 stroke engine sheding a prop with no loctite).
