The following examples explain how to use
the thread dial and the thread dial chart.
TPI Ending in ⁄ : For threading TPI ending in
1
2
use only the number 1 on the thread dial (see the
example in Figure 85).

Odd Numbered TPI: For odd numbered TPI, use
any pair of opposite numbers on the thread dial
(see the example in Figure 86).

Important: Once a number has been selected,
continue using that number or its opposite on the
dial.
For example:
• If you make the first threading pass and select
1, then all following passes you must select
the 1 or its opposite, number 5.
• If you make the first threading pass and select

either the 3 or its opposite, number 7.
