how many rockwell's in a Benz lug bolt?

I need to get some MB bolts threaded further up the shaft (don't ask ... or if you're curious, see my post over on the main page.) Local machine shop says it can be done with their single-point carbide bit, but not if the lug bolts are too hard. Anyone care to guess the "rockwell" hardness for '99 E320 standard bolts? Thanks in advance.
