Harmonic Balancer bolt

Looking for options on turning sbc super stock motor by hand. Pretty much have used a high grade 7/16? fine thread bolt in the past, but with today?s spring pressure, and not wanting to always remove plugs my comfort level using just a bolt is not high. I?m concerned using a long bolt with 5/8? socket head going thru pulley for alternator, crank trigger wheel and balancer is super stressing threads. Is there something out there that?s keyed with large nut to relieve stress on threads? What are others doing to turn by hand? Thanks. Ed
