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.

Every tool comes with a certificate of calibration stating the clutch has been tested for accuracy for the different adjustable ranges.

Accessories for the 4730 consist of screwdriver bits.
