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.
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.
You will not find an auto repair shop, an automotive training course or even an auto mechanic school that is not well stocked with a wide variety of combination wrenches. When it comes time to do car repairs or other basic mechanical jobs, the first tool in your kit should be the combination wrench. Solid, basic, sturdy and dependable the combination wrench doesn't have moving parts and is designed to withstand impacts on even the most demanding jobs.
As everyone who has been through an apprentice program knows, bolts are used in construction, manufacturing, and assembly of almost everything. By having a combination wrench set at the ready, you can show that you have the ability to place or remove a bolt easily and efficiently.
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.
