TAW AND TAS SERIES
Note: For a fixed length head, head length entered is offset length measured from center of
drive to center of fastener.
Offset
Note: For an interchangeable head, head length is measured from locking pin to center of drive.
SET HEAD LENGTH is set during calibration. If a different length head is used, enter new head
length and offset is calculated automatically.
Note: For an interchangeable head with an adapter, head length entered is sum of head length
and offset length.
USE OF NEGATIVE OFFSETS
Note: Enter a negative value for offset when used in reverse direction with flex head or when
calculating sum of interchangeable head and offset lengths.
Offset
When length of an offset (or sum of head minus offset for interchangeable head) is negative, maximum
fastener target is limited by following formulas:
