Part #20191
Designed For:  

The 4750 preset hand torque screwdriver was designed for the customer who desires a precision manual torque tool which has an overall accuracy of 3%. The design incorporates a bi-directional, ball-type clutch mechanism with working torque range of 0.2-12.0 in lbs (.02-1.35Nm). The 4750 comes in a powder-coated blue housing. Each tool comes with five colored bands (yellow, blue, red, green and orange) for torque value identification. The ergonomically designed handle fits comfortably into the operator's hand for ease of operation. This model come with a 1/4" female hexagon drive, and an adapter is available for conversion to 1/4" male square drive (P/N 20191) for use with sockets. The tools were designed for the manufacturing engineer who wants to randomly check finishing torque values on the line or for the Q.A. who is checking the final torque on a finished product. The tools are also being used in low-volume assembly where the cost of a motorized tool is not practical but the need for precise torque values is still required. The 4750, like our pneumatic power tools, are manufactured in our U.S. plant.

 
Clutch:  

Any tool can have the clutch set to a torque value at the factory, if requested. Any tool which is set at the factory will receive a certificate of calibration sheet which is N.I.S.T. traceable.

 
Accessories:  

Accessories for the 4750 consist of foam grips and screwdriver bits.
