🔍 Key Concepts

• Manufacturer’s specified tension for bolts and why it matters on engine components • The difference between tools that apply measured force versus tools that just grip or turn • Which hand tool can be set to a specific value (foot‑pounds, newton‑meters, etc.)

💭 Think About

• Ask yourself: which tool is designed to let you know when a precise tightening force has been reached, rather than just giving leverage? • Think about which of these tools is commonly used when over‑tightening could damage bearings, studs, or threads in an engine. • Consider where you have seen bolt‑tightening procedures that specify a number like “90 ft‑lb” or “120 N·m” and what tool you would normally use to achieve that.

✅ Before You Answer

• Identify which option is specifically associated with measuring or controlling torque, not just turning a nut or bolt. • Eliminate any tools that are primarily designed for special access or shape (e.g., offset or hook) rather than controlled tightening. • Confirm that the tool you choose can be set or read to a numerical value that matches the manufacturer’s specification.
