Optimum Thread
performance with
Wire Thread Inserts
is achieved when
the inserts are
installed 1/2 to 1
pitch below the
surface of the
Tapped Hole. This
means that the
actual length of an
installed insert is
equal to dimension
DL less 1/2 to 1
pitch. Dimensions
AL and CL allow for
tap end clearance
of finishing Taps.
When using
Bottoming and
Spiral Flute Taps
these dimensions
maybe reduced by
an amount equal to
2 thread pitches.
Any counterbore
depths must be
added to these
dimensions.
