Typically, a pipe wrench is composed of an upper hook jaw and a lower heel jaw, both connected to a flat handle. The lower jaw is adjustable to the size of the metal object. Forward pressure on the handle pulls the jaws closer for ease of gripping and turning. Usually made of aluminum or steel, pipe wrenches are available in various sizes measured by the length of the handle.
Of the two types of torque wrenches, the micrometer wrench is definitely the more accurate. Typically, they are rated as being accurate to four percent of torque set. However, this accuracy can easily be lost if the wrench is not reset to zero before storage. Beam wrenches don't have this possibility of losing their accuracy, but are less accurate right out of the box. The accuracy of these beam wrenches is typically 12 percent, but can be less on higher torque settings, especially if the operator's hand is shaking from the pressure they are applying.
You can think about the purpose of the tool before deciding on the kind of wrench to meet your requirements. Adjustable wrenches are handy tools in a home and you can invest in each of these varieties to undertake all types of repairs in your home quickly and easily.
The combination wrench is the perfect tool for an automotive kit, industrial shop usage or household toolbox. A combination wrench also known as a spanner, is a wrench with an open face on one end and a circular grip on the other.
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."
