A combination wrench set is useful for the aspiring motor mechanic as well as industrial mechanics, carpentry jobs, household repairs, automotive repairs and for common tasks such as furniture assembly.
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."
When tightening a bolt to the proper torque, it is essential that your hand which is pulling the wrench is cantered on the handle of the wrench. Having it too close or far from the socket actually affects the ultimate torque value you are tightening to. Moving your hand closer to the socket reduces the total "foot-pounds" of torque you are applying, while moving it away, closer to the end of the wrench increases the "foot pounds of torque you are applying."
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.
The right mechanics tools make the difference between an easy job and a difficult one. A mechanic or carpenter is defined by their tools and having the highest grade tool set, complete with combination wrenches, prepares you for any job. The complete mechanics tool set includes wrench kits for automotive jobs, bicycle repair and even specialized work involving foreign automobiles and RV repair. Accessories for spanners that you may want to add to your tool set include cases, wrench grips and wrench holders.
