The 4740 Series was designed for the customer who desires a manual
torque tool which is adjustable externally but still has an overall
accuracy of ±5%. These screwdrivers incorporate a bi-directional,
ball-type clutch mechanism with a working range of 5-50 in. lbs.(1.0-6.0Nm).
The mechanism in both tools is automatically reset and smooth in
action, this eliminates over-tightening. The tool come with a 1/4"
female hexagon drive. An adapter is available for conversion to
1/4" male square drive (P/N 20191) for use with sockets. These tools
are perfect for the engineer who is trying to determine the correct
torque values for assembly or prototype work. The maintenance and
service departments find these tools essential in their everyday
jobs of repairing and servicing.
