THREAD SIzING
The
t
key allows you to enter a Thread Size and then toggle
through the various available Thread characteristics, as shown
in the tables provided later in this section.
When using the
t
key, the rst entry is considered the
Thread Size (1 mm to 300 mm). After entering the Thread
Size, the Pitch is required (less than or equal to 10). If the
entered Thread Size is a standard size, continuous presses
of the
t
key will toggle through the available Pitches. Once
the desired Pitch is reached, pressing
O
stores the Thread
Size. If the Thread Size you enter is not a standard size or if
you have a non-common Pitch, you will need to directly enter
the Pitch value, pressing
t
after entering it in order to store
the Thread Size.
Note: Entries outside of the ranges mentioned above will result in an
Entry Error.
The following tables list the available Thread characteristics
provided by the Thread Size function. Note that there are two
separate listings, one for Internal Threads and one for External
Threads. The listing shown within the Thread Size function
is determined by the set Thread Classication (see Thread
Classication section).
Internal Thread
Thread Size Minimum Pitch Diameter
Cut Tap Drill Size* Maximum Pitch Diameter
Roll Tap Drill Size* Minimum Minor Diameter
Close Fit Drill Size* Maximum Minor Diameter
Free Fit Drill Size* Minimum Major Diameter
* If the resulting hole size is greater than 50 mm, the actual hole size
will be displayed instead of adjusting to the closest Drill Size.
