Which operation is typically performed with a wrench?

• A. Tightening or loosening nuts, bolts or screws
• B. Drilling holes
• C. Sanding surfaces
• D. Polishing edges

Answer: (A)

A wrench is designed to apply torque to fasteners, allowing you to tighten or loosen nuts and bolts (and related fasteners). This is exactly the operation described in the question—the turning action used to secure or release hardware. Drilling holes requires a drill, not a wrench. Sanding surfaces uses abrasives and a sander or sandpaper to smooth material. Polishing edges involves polishing compounds and a polishing tool to create a smooth, shiny finish. So the wrench’s purpose—torquing fasteners—is the best fit for this scenario.
