    Image of Product. Front orientation. Torque Wrenches. Nonsparking Torque Wrenches.
    These wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. Set the desired torque and the wrench indicates when it's reached with an audible click. To relieve pressure on the spring and maintain calibration, set torque to the lowest reading on the scale when not in use.
    Torque—You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.
