Wrenches are used to exert a twisting force on

• A. Bolt heads, nuts, studs, and pipes
• B. Nails
• C. Screws
• D. Pins

Answer: (A)

Wrenches are designed to apply torque, a twisting force, to fasteners that you turn to assemble or disassemble parts. They grip bolt heads and nuts (and the threaded studs they fasten) with flat, hex, or square surfaces, letting you apply leverage to tighten or loosen. Pipe wrenches grip the outside of round pipes to twist fittings. Nails are hammered in, screws are driven with a screwdriver or driver, and pins are inserted or removed rather than turned with a wrench. So the best use is to turn bolt heads, nuts, studs, and pipes.
