The Stanley IW16 Impact Wrench is a 1" square drive underwater hydraulic wrench with adjustable impact intensity from 500-2500ft.lb. (680-3400Nm). Stanley Impact Wrenches can be operated over wide flow ranges, in the case of the IW16, 26-45lpm. Used by commercial divers for underwater nut, bolt, and anchor bolt driving and other medium to heavy duty applications.

Adjustable Impact Intensity of the Stanley Hydraulic Underwater Impact Wrench IW16 makes it ideal for a wide range of uses by the commercial diver. Rugged swing-hammer impact mechanism provides easy servicing for reduced maintenance costs and greatly reduces the transmission of torque to the commercial diver reducing fatigue through repetitive tool operation.

The Underwater Impact Wrench Stanley IW16 also features a large "D" handle and feathering On/Off Valve allow the commercial diver to control the amount of energy to the underwater tool, providing more control and ease of handling. Standard reversing valve provides instant changeover from forward to reverse, increasing commercial diver efficiency.
