Which tool is used to install or remove external wrenching bolts?

• A. 12 point socket
• B. Hex wrench
• C. Torx screwdriver
• D. Pozidriv screwdriver

Answer: (A)

When you need to install or remove bolts that have their wrenching surface on the outside of the head, you want a tool that fits over the outside of the head and grips it securely. A 12-point socket is designed for that kind of work because it encloses the bolt head and makes contact at multiple points, which helps transmit torque cleanly and reduces the chance of rounding the corners, especially in tight spaces. This makes it a versatile choice for external wrenching bolts, since it can engage hex heads reliably and still fit in cramped areas. Hex wrenches are for bolts with internal hex recesses, not external heads, so they won’t engage the outside shape of an external wrenching bolt. Torx drivers work with star-shaped recesses and are used when the bolt has a Torx pattern, not a standard external hex head. Pozidriv drivers are for a specific cross-head pattern as well and don’t fit external hex heads.
