Checking Thread Length

1. Thread is cut to proper length when end of pipe is
flush with edge of dies (Figure 11) .
2. Die Head is adjustable to obtain proper thread di-
ameter. If possible, threads should be checked with a
thread ring gage (Figure 11) . A proper thread is cut
when end of pipe is plus or minus one turn of being
flush with face of ring gage.
