box-end wrench
Quick Summary
A box-end wrench is a tool with a closed ring or socket that fits over a bolt head or nut. Unlike open-end wrenches, which grip the sides of a nut, box-end wrenches enclose the entire fastener. These wrenches typically have 6, 8, 12, or 16 points inside the head, allowing them to fit hexagonal or square nuts. Their thin sides make them useful for nuts in tight or hard-to-reach spaces.12
