Machinists needing a bottoming tap for fine threads

This tap suits users cutting 7/16-20NF threads to a G H3 tolerance in steel, aluminium or plastic. It is not intended for buyers who need a taper or plug chamfer for starting threads, nor for those requiring a different thread size, pitch or pitch-diameter limit.
