The 4730 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 20-120 in. oz.
(0.15-0.9Nm). The mechanism in both tools is automatically reset
and smooth in action, this eliminates over-tightening. The tool
comes 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.
