If you are concerned about stripping the porcelain, wrap the tape (painter or masking) around the nut and then apply gentle pressure.

Before you call a professional to remove stubborn nuts, try using a saw. Before you use the saw, however, tape cardboard around the toilet bowl rim to protect the porcelain.
