Hi Nate (and Stefan) -- As an American, I have to deal with SAE, MS, NAS, (etc) types of screws/bolts, tapped holes, and nuts (which is why I have created so many Libraries that are posed under Resources). My argument is that I should be able to define a Hole Feature based on a Fastener's definition/placement. Thus if I have a (say) M6 screw protruding (let's say) 11 mm deep into a component, a (say) 14 mm (Full Thread) deep tapped Hole Feature should "derive" from it. Should a M6 bolt pass through a component, then a ø6.5 mm (or ø7 mm) clearance hole should be aligned with that bolt. [And, of course, Pilot Holes for Taps should allow for tap tips and chip allowance.]
