Dial Thermometers use a helix coiled bimetallic strip located within the thermometer stem to measure temperature. Dial thermometers are calibrated to a known temperature by adjusting a hex nut located under the dial. Dial thermometers have a probe that is inserted into the material being measured with a dial and read from above.

The Dial Type Wrench provides an excellent solution for many applications. The wide range of scales makes selecting the appropriate tool easy. Accurate to 2% of the reading from 20% of full scale to full scale clockwise and counterclockwise, the Dial Type Wrench is the most accurate torque wrench family. The Dial Type Wrench is the only wrench that is not affected by the hand-hold position on the wrench. Due to increasing use of lighter and softer metal, alloy, and even plastic components, torque wrenches are being used more and more to measure the amount of tightening force (or torque) applied to corresponding fasteners. Precision tightening of bolts is necessary on automobiles, power mowers, outboard motors, household appliances, and many other devices.
