Wouldn't a flywheel,pressure plate,or ring gear be a "loaded in shear" application? Some flywheel bolts have a shoulder built in to keep it from shearing off. Most import pressure plates have pins to help locate the plate and provide additional shear protection from what Toyota engineers have told me.

I'm not educated, but IMO the clamping pressure keeps those parts from moving, unless, the bolts loosened up. Like that alignment pin in a camshaft, it won't hold the gear from turning the bolt does by clamping. I was told a six penny nail has a 2000 pound shear capacity. What supprized me is the lift plate that's bolted to an intake that will support a 500 pound engine with four little 5/16 bolts and nuts.
