What is a torque wrench and when should you use it?

• A. A tool for tightening fasteners to a precise torque, used whenever a specific torque is required
• B. A tool for measuring amperage
• C. A tool for cutting metal
• D. A tool for scraping surfaces

Answer: (A)

A torque wrench tightens fasteners to a precise torque, ensuring the clamping force matches the design specification. Use it whenever a specific torque value is required to achieve proper joint strength and avoid damage from over- or under-tightening. This is essential on components like engine bolts, wheel studs, flanges, and other critical joints where the exact amount of tightening matters. Set the desired torque, apply steady force, and stop when the tool indicates the target has been reached (by a click, beep, or readout). Regular calibration helps maintain accuracy, and always follow the specified tightening sequence and lubrication conditions. Without a torque wrench, you can’t guarantee the exact torque, which is why this tool is the right choice for these jobs.
