Square Drive Torque Tool Testers
Check the accuracy of torque wrenches and screwdrivers—place your tool onto the tester with the included square drive connector and turn. The main pointer shows torque as it's measured; the memory pointer shows the maximum torque reached. Use these testers with hand tools only.
Note: The accuracy ratings do not apply to the lower 20% of the torque range.

High-Accuracy Torque Tool Testers
These testers have a digital display and are accurate to ±1%. Place your torque wrench or screwdriver onto the tester with the included square drive connector and turn. Testers display torque as it's measured and the maximum torque reached. They also show the first torque peak reached to ensure accurate readings when testing click-style wrenches. Use with hand tools only.
Note: The accuracy ratings do not apply to the lower 10% of the torque range.

Data-Recording Torque Gauges
Use these gauges with changeable sensors and square-drive sockets (sold separately) to display, collect, and download torque readings. They display torque as it's measured and the maximum torque reached. Gauges can also be used to convert any hand-turned square drive tool into a precise torque-measuring tool.
Note: The accuracy ratings do not apply to the lower 10% of the torque range.
Wrench-attachable sensors fit between your wrench and socket. Use with hand tools only.
Hand-turned sensors don't require a tool; place into your socket and turn them with your hand.
