McMaster-Carr......combination drill bits/taps0

do they make a 1/4 npt?
I can't find one large enough at McMaster Carr.
I will look at GreenLee.
Thanks.0 -
Have not seen them in NPT sizes. A truss head bolt will work in PVC, though I would prefer fine threads.
We have used 1/4" thread-serts in single wall vent pipe.0 -
