2. Extension bar : Code No. 874535
The extension bar is convenient for working in very restricted spaces or when
the socket provided cannot reach the bolt to be tightened.
CAUTION:
When the extension bar is used the tightening torque is reduced slightly com-
pared with the ordinary socket. So it is necessary to operate the tool a little
longer to get the same torque.
3. Universal joint : Code No. 955088
The universal joint is convenient for impacting nuts when there is an angle
between the socket and wrench, or when working in a very narrow space.
NOTE:
Specifications are subject to change without any obligation on the part of the
HITACHI.
