Compared to an open-end wrench, a box-end wrench engages the fastener from how many sides?

Explanation:
A box-end wrench engages the fastener from all sides because its closed ring fully surrounds the head and makes contact with every face as you turn. This 360-degree grip distributes torque across the six flats of a hex head, keeping the fastener more secure and reducing the chance of slipping. In contrast, an open-end wrench clamps on only two opposite faces at a time, leaving other faces exposed and more prone to slipping. So the box-end wrench indeed engages from all sides.
