How does a box-end wrench surround a nut or stud?

• A. On all sides
• B. On two sides
• C. From the top only
• D. From the bottom only

Answer: (A)

A box-end wrench forms a closed loop that completely encloses the nut or stud, providing contact on all sides. This 360-degree grip means the wrench engages the nut on its faces around the circumference (usually six faces for a hex nut), distributing torque evenly and reducing the chance of rounding the corners. Because the grip surrounds the fastener rather than just touching from two sides, it resists slipping and can transmit higher torque more securely, which is especially helpful for stubborn or tight fasteners.
