When tightening a bolt, being able to measure torque is important. That's where a torque wrench comes in handy. It is similar in design to a regular socket wrench, except a torque wrench has an additional rode that moves along a meter to display the amount of pressure being applied to a bolt. They are available online (http://www.amazon.com/wrench-torque-wrenches/b?ie=UTF8&node=559968) or at
. local hardware stores such as Lowes or Sears.
