The box end wrench is usually

• A. Double-ended with a closed socket that fits over the head of a bolt; 12-point is common; may be used on square and hexagonal bolt heads
• B. Open-ended with two parallel jaws
• C. Adjustable with a movable jaw
• D. Ratchet-equipped with a socket reel

Answer: (A)

Box-end wrenches grip by enclosing the fastener head, giving a secure, full-contact grip that spreads torque around the head and helps prevent rounding. They’re typically double-ended, offering two sizes on the same tool, and the interior is often 12-point, which lets you engage hex and even square heads from more angles in tight spaces. This combination makes the tool versatile for different bolt shapes and working in confined spots, unlike open-end, adjustable, or ratchet-and-socket styles that don’t provide that closed, full-ring engagement.
