RE: Torquing thru bolts
maximum torque is proportional to all of the same things: If you squisch the two (or three) beams together to tight so the bolt head or bolt and washer or plate is pulled into the wood, the wood is destroyed (visually of course) and structurally. Wood will tend to relax also under years of drying out and continued compression.

RE: Torquing thru bolts
It is for a pedestrian guard post application, so I don't need a lot of clamping (there is a force-couple resisting the load), but I always worry about the contractor going out of their way to install it like a moron, and I would rather not have a jiggle-y guard system - even if it can handle the ultimate loading.
