Default Re: Which tap and die set

Ford used rather tight clearance tolerances on many fasteners. If you buy the average tap/die set it will be fit class 2A/2B and you will ruin parts if you use the taps/dies to clean up nicked threads. You need a set with 3A(external) & 3B(internal) clearance tolerances.


My go-to for taps/dies with the clearance specs I want is MSC Industrial Supply Direct Co. Inc. (US)
