Making a Screw Thread

In respect to thread standards, there are a metric thread (M), a parallel thread for piping (PF), a taper thread for piping (PT), and The nut is made from a larger stock witch has a hole drilled through it that is slightly larger than that of the rod diameter. is made with threads, and another piece is made with clearance holes, which have bigger diameters than that of the screws. (3) Always use a cutting oil.
