The Monkey wrench Otherwise known as gas grips, this is a traditional type that comes with a straight and long handle. The tool's forged metal makes it highly durable. This type wrench is mostly used on projects of large scale. In this type of wrench, the handle is extremely smooth and the size of the jaw can vary. Some of these tools are so large that they can even grip a large pipe of say, 3 inches.
If you are buying a torque wrench for your car, you should buy a 1/2 inch square drive tool, as 3/8 in drive tools only work on lower torque settings (typically below manufacturer's specifications). Adapters are available to reduce the 1/2 inch square drive to 3/8 inch square to fit the more common socket size that most people have.
There are two basic types of torque wrenches on the market, what are called "beam" wrenches and "micrometer" wrenches. Beam wrenches count on the built-in flexibility of any material. As torque is applied, the wrench flexes, while another rod, with a pointer at the end, indicates torque being applied on a scale.
Torque wrenches are precision tools and should be treated as such. Although most micrometer wrenches have a reversible ratchet head, they really should not be used as a ratchet, and especially not as a breaker bar. Most people who break their torque wrenches do so by trying to loosen an overly tight bolt with it. This overly stresses the internal mechanism, causing it to break, especially if the micrometer isn't set to a higher torque value than the pressure that is being applied.
Micrometer wrenches are pre-set to the required torque on a vernier scale. An internal spring loaded mechanism measures the torque. When the bolt is tightened to the desired torque it "clicks."
