One may also clamp a flat piece to the table by drilling, counterboring and clamping it down with socket head cap screws and T-slot nuts, then skim the surface, drill and tap and then screw your part down. It does not need to be any bigger then the part itself, if you have the Z clearance to do it in a vice then there is certainly room to do it screwed to a sub 1" high fixture on the table.
This sort of simple flat fixture may be reused many times, simply bolt it down to the table and skim it again, drill and tap new holes for the new part and have at it.
Good Luck with your project.
If one is overly concerned about accurately "tensioning" threaded fasteners a torque wrench is about the least accurate method (aside from a large handheld non-torque wrench) yet the only method available for general work.
For those hobbyists suffering from crippling OCD about accuracy , Rotabolt as well as several other manufacturers such as Maxbolt™ make exactly what you seek. However you will not be at all happy with the cost.
