Since you are buying new bolts anyways, try and get some shoulder bolts like these http://www.fastenal.com/web/products/details/26330 they will let you thread in only enough to engage the threads and help prevent you from damaging the coils. They are a little more costly, but it’s what the factory puller sets use.

Edit: please note, those are not the correct bolts, just an example of what you probably want to look for
