Not sure what you have posted is valid, IF you are using the original bolt with the thick washer (without the balancer installed) THEN you should install a few thick steel washers on the bolt (before you install the bolt in the crank). THIS will keep the bolt from being wedged in the crank and possibly stripping out some threads.
The Crank Bolt was designed by Engineers to have some distance BEFORE the bolt bottoms in the drilled and tapped hole when the balancer is installed.
I use a factory "no balancer ring" hub to mount my large degree wheel and a similar set-up (minus the degree wheel) to just turn the engine over. You can remove the bolt by hand almost when you do it that way. The washers will work fine though too.
Cranking on the Harmonic Balancer Bolt (no balancer) is almost guaranteed to cause thread issues inside the crank over time.
