TSD650-BT Benchtop Systems

Benchtop Systems for Click Wrench Calibration

A.K.O., Inc. TSD650-BT Benchtop Systems for click wrench calibration are mechanical torque loaders with capacities up to 800 lbf·ft. These systems provide precision, speed, and accuracy in the calibration of manual torque tools, while reducing the overall system footprint and the amount of labor required to perform a traditional calibration of a torque tool. A loader system limits the human error that is inherent in traditional calibration methods by using a precision ball screw to smoothly apply the torque load to the tool. The loader is fabricated from welded aluminum plates, and custom machine parts for a long operational life, while maintaining A.K.O.’s high standard of quality. The TSD650-BT uses the proprietary advanced TSD6500 Digital Indicator that can be combined with up to 8 Transducers to provide continuous coverage over your entire operational torque range. 


The TSD650-BT Torque Loader Systems are versatile torque calibration systems with a wide variety of adapters and accessories available. With the appropriate accessories these systems are capable of calibrating many types of tools, such as Click Wrenches, Beam Wrenches, Dial Wrenches, Digital Torque Wrenches, Torque Watches, Torque Screwdrivers, Electronic Torque Tools, and Tensiometers.


The TSD650-BT systems are user driven with a hand-wheel to provide torque manually. The torque forces are self-contained by reacting against a two-way (CW, CCW) adjustable reaction post on a stainless-steel reaction slide allowing the reaction point to be set to any position. The tool being tested and calibrated is installed on the selected Torque Transducer’s square socket or using an appropriate Adapter. Apply torque to the tool under test by turning the hand-wheel CW or CCW as appropriate until the torque value is reached. 

TSD2060-BT Benchtop Systems 

The TSD2060-BT Benchtop Systems use the loader casting from the traditional TSD2060 Manual Click Wrench Calibration Systems as a high-capacity bench mounted system capable of up to 4000 lbf·ft of torque.
