About This Product

TEKTON micrometer torque wrenches are designed to instill confidence in the wrench's accuracy and control during operation. They are calibrated to be accurate within ±3% for both clockwise and counterclockwise directions and certified to the ISO standard for the full listed range (20 - 200 in-lb), unlike torque wrenches calibrated to ASME standards, which do not require calibration below 20% of the listed range. The single half-moon pawl maintains 9 teeth engaged with the gear at all times, so it won't skip under stress. The internal components are the same design and construction as all of our 90-tooth ratchets. The 4-degree swing arc reduces the length of travel at the end of the wrench handle between each click. The micrometer scales are laser-marked in bold fonts on the satin-finished handle body, making them easy to read. The collar springs into a locked position that holds your setting and prevents accidental movement during operation. There is no thumb knob to tighten at the end of the handle. A deep, sharp-cut diamond pattern on the surface of the handle creates a coarse texture that won't slip in your hand. The case provides safe transport for the torque wrench and protects it from drops. Each item in the case has its own place and is held securely.The case is made of high-density polyethylene (HDPE), and the latches are polypropylene (PP). Includes a serialized certificate of calibration.

Highlights

  • Accurate within ±3% for Both Directions - The actual calibration accuracy will be stated on the certificate for your wrench, but will be no worse than ±3%
  • Full-Range Calibration Using the ISO Standard - Since this torque wrench is calibrated to the ISO standard, it also meets and exceeds the ASME standard
  • Serialized Certificate of Calibration - Includes serial number, test results, and test equipment and conditions
  • 90-Tooth Fixed Ratchet Head - The single half-moon pawl maintains 9 teeth engaged with the gear at all times, so it won't skip under stress and the 4-degree swing arc reduces length of travel
  • Easy-to-Read Micrometer Scales - The single-unit scale is marked with high-contrast laser markings on a satin-finished handle body to reduce glare

Questions & Answers

Does it give an audible “click” or do you feel it

Answer This Question

This is James with Tekton. Our 1/4 inch drive dual-direction micrometer torque wrench produces both an audible click and tactile response when reaching the set torque value. At lower settings, the sound and feeling may be less pronounced.

    excellent wrench and support
    After buying a discontinued Tekton torque wrench and then not using it for two years, the ratchet head began occasionally slipping. Expecting little, I called Tekton support, which answered on the first ring. With absolutely no hassle ~ just a photo ~ Tekton promptly sent me a replacement torque wrench from its current products. The replacement, this torque wrench, works flawlessly. Thank you, Tekton!

      Great torque wrench for the price. Even at low torque values you can still feel the "click".
