I am getting close to my first engine start (probably in the next month or so) and was wondering if I could use grade 3 hardware store bolts for the catto propeller? I haven't bought the final bolts yet because I haven't done my Weight and Balance (no paint/engine baffling ect.) and don't know If I'll have to put a 20lb crush plate on the front like others here on VAF. Should I use these bolts or wait to start the engine until the very end of the build when I have the right propeller bolts? Thanks for the help!
