3ds Max Modeling :: Centering Bolt In Hole?

Q1: I am trying to do something that has always baffled me in 3ds Max. Something very easy to do in AutoCAD! Being a technical animator alot of my client supplied models are often missing components. Most notably bolts and other fasteners! This tends to look bad if they are missing so I take the time to put the proper fastener (in the EXACT center) of each hole. Pretty easy to do with AutoCAD snaps and a solid model but what about 3ds max?

Q2: The motor when imported from an ACIS file has the pivot set to the center of the motor. Unfortunately this pivot is off center of the motor shaft because of the electrical box on the side. How can I move the pivot to the center of the motor shaft accurately? Can I somehow move the pivot to the center of a sub-object shaft selection? Having this pivot (or an appropriate dummy object) at the exact center is critical when aligning other rotating objects. Otherwise the wobble looks bad!

The attached images is a motor (body object) with four bolt holes in the base that need to be filled with the bolt (4 times). how I might achieve this easily as well as Q2. Keep in mind that I will be doing this for hundreds of bolts in some cases.
