Yep tap cons are genreally the best for anchoring into concrete. Excellent advice if they be bind up in the hole they will snap. So drill the proper diameter hole, set your drill on the lowest tork setting and work your way up or use a ratchet by hand. Shooting in a fatsener such as a Hilti can be good also but can cause damage if it is to close to and edge and older concrete can sometimes just blow apart.
