Thread forming zerks are made for untapped holes. Saves manufacturing steps. Special drivers may be required during the manufacturing process. Suspect their lead thread might be different than NPT. A NPT thread zerk might fit a thread formed hole?
Might have replaced a few?? Unintentionally, With NPT??, But never bought any to install.
