Product Questions

Q.
What are the measurements of the actual brass screw? I just ordered a 3/4" OD thinking that the OD measurement was of the brass screw, but it turns out that the OD is of the anode. The brass screw is way too big. I need a 2" long anode that goes with a 3/4" screw. Unsure whether this is the 1/4" or the 5/8" OD measurement. Can you please advise? thanks
