What type of wrench is specifically used for rounded nuts?

• A. Open-end wrench
• B. Box-end wrench
• C. Socket wrench
• D. Crevice wrench

Answer: (B)

A box-end wrench is specifically designed to grip the entire face of a nut or bolt head, making it particularly effective for rounded nuts. It has a closed loop that provides a greater surface area to distribute the force applied during use. This design minimizes the risk of slipping, especially on fasteners that may have become worn or stripped. Box-end wrenches often come in different sizes to fit different nuts and bolts, and their design allows for good torque application while protecting the edges of the fastener. This is crucial when working with rounded nuts, as standard open-end wrenches may not provide the same level of grip and can easily slip off, further damaging the rounded surfaces. Other types of wrenches, while useful for different scenarios, do not provide the same level of efficiency or safety as the box-end wrench when it comes to handling rounded nuts.
