Installing Dies in
Model 816/817 Die Heads
The Semi-Automatic Die Head (Figure 10) for right hand
threads requires four sets of dies to thread pipe ranging
" through 2". One set of dies is required for each
from 1 /
8
of the following pipe size ranges: (
") and (1" through 2"). Bolt threading requires a
and 3 /
4
separate set of of dies for each bolt size.
1. Depress handle so that camplate rests (Figure 10 –
Model 816/817 Die Head) against the stop. (As
shown).
2. Lay the Die Head down flat on a table or bench
with the numbers facing up.
3. Pull up on the plunger knob and push the handle all
the way to the left.
4. Select the correct dies for the size desired. (Size
marked on the back end or face of the dies.)
5. Numbers on the Dies must correspond with those on
the Die Head Slots. Insert Dies to the line marked on
the Dies – numbered edge up.
6. Rotate the handle back to the right so that the plunger
knob pops back down flush against the Die Head.
7. To set or adjust for desired size loosen the screw for
the desired position block size, move the block to the

Checking Thread Length

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

NOTE! If a ring gauge is not available, a fitting can be
used. This fitting should be representative of
those being used on the job. The pipe thread
should be cut to obtain 2 to 3 turns hand tight
engagement with fitting. If pipe thread is not prop-
er diameter the index line should be moved in the
direction of the OVER or UNDER size mark on
size bar. (Refer to " Installing Dies In Die Heads ").
