Accurate to within ±1%, these torque testers are often used to check the accuracy of torque wrenches and screwdrivers on assembly lines.

Finger-tighten the three-jaw chuck onto a torque wrench or screwdriver, then twist either the gauge or tool to check the tool’s accuracy.

Measure the force of hand and non-impact electric torque screwdrivers to keep fasteners from failing due to under or overtightening.

Calibrate torque-limiting power tools such as air-powered and impact drivers.

Attach a socket to the 1/4" square drive tip. These tools have a dial that shows how torque measurements change as you turn the driver. Use to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners.

A green light and a beep alert you when you've reached 90% of your set torque, and a steady tone sounds once you've hit your target. Set your torque in cNm, cm-Kg, or in.-lbs. and quickly check the LCD for real-time measurements along the way. A red light warns if you begin to overtighten.
