I'm sure this falls under the category of "everyone knows about this but me", but after fumbling with the key that Simms provides to install studs in Vibram soles (I had a tough time applying sufficient pressure to get the stud screws to bite), I grabbed my trusty Makita variable speed 3/8 drill, chucked the studs and was done in 5 minutes; just used the key for final tightening.
