Choosing a 1/2-inch torque wrench

Use the points below as a practical starting point, then check the individual product page for the full technical information before ordering.

  • Choose a torque range that comfortably covers the specified tightening value rather than operating continually at the extreme of the scale.
  • Use the correct units and follow the vehicle or equipment manufacturer torque specification.
  • Apply force smoothly at the designated handle position and stop when the wrench indicates the set torque.
  • Store and maintain the wrench according to the manufacturer instructions and calibrate it where accuracy is critical.
