I think I do more single-point threading than tap or die threading.? ? Certainly in larger thread sizes (1/2" and up), and certainly not in small thread sizes (less than 1/4").? ? Projects I do with large fine threads generally require single-point threading, especially if fine fitting is desired.? ?I have a project to do with 7/8"x32tpi threads.
The images are of 1/2x20tpi threads - with no discernable play and smooth turning.? ?The male threads are on 3/4" brass rod and the nut is gold iridite (yellow chromate?) finish grade 8.
It's the beginning of a drain spud for a furnace humidifier.? ?It is since drilled through 0.280" and has a 3/4" male 45 degree taper seat on the left side.? ?Does it need to be that good?? ?No, but I want it that good.? ?After all, it's a hobby!
