American Assembly Tools

Our Specialties (Fast, Flexible, Rugged, and Reliable)

American Assembly Tools Inc. (AAT), manufactures, sells and services a full line of in-line and angle nut runners with torque ratings from 10 Nm to 2000 Nm. We offer a variety of operator and automatic shut-off controls that makes it easy to integrate our products into the simplest or most complex assembly system.

Speed-Shift™ nutrunners are the headliners of AAT's product line. AAT combines Speed-Shift™ with high torque gearing to provide remarkable increases in productivity. High torque nutrunners are notoriously slow. 25 rpm at 1000 Nm is typical. With AAT's Speed-Shift™, 250 rpm is possible at 2000 Nm. With speeds that are 3 to 20 times faster, energy consumption is one third to one tenth that of conventional air or electrical tools. With this simple mechanism, the tool downshifts from a high rundown speed to a slower speed for final tightening. Shifting is dependent only on torque and is completely automatic. We also offer Speed-Shift™ nutrunners equipped with our special Flat-Angle designs to fit into restricted spaces with torque output as high as 2000 Nm.

We are a member of the Triad Capital Group of Companies along with Total Automation.  Dedicated to manufacturing in the US
