hello everyone, alright, so basically, i need to tap a threaded hole for one of the front motor mount bolts. when i screw it in, it goes to the end and then when i try to tighten it, it keeps on spinning off nothing. it on a 2001 prelude by the way. the wrench size used to tighten/untighten the bolt is size 14, but i dont know how big the screw part actually is so i dont know how big of a tapper i should get. providing me with the size of the screw part of the bolt would be prefect, but if you have any other recommend. let me know.
