Yes, for any job where bolts have a specified torque, such as wheel nuts, brake calipers, suspension and engine parts. Over or under tightening can cause parts to fail or come loose.

Set the wrench to the specified torque, fit the socket, and pull smoothly on the handle until it clicks or indicates the set torque. Don't keep pulling after the click. Store click type wrenches at their lowest setting.

Choose one whose range covers the torques you work with most, ideally in the middle of its range. Many home mechanics use a smaller wrench for engine work and a larger one for wheels and suspension.

Follow the maker's guidance. Many recommend checking calibration about yearly, or sooner if it's been dropped or used heavily.

Commonly useful specialty tools include a brake caliper piston tool, a ball joint separator, a flare nut spanner, a bearing puller and a multimeter. Buy them as jobs come up.
