Westward 3XU42 Combination Wrench These combination wrenches feature a 12-point box end with additional grooves that make it easier to connect with the head of the fastener and allow for connectivity at more angles, providing better accessibility compared to a 6-point wrench. The opposite side has an open-end design, allowing for top and side access to the fastener, unlike the box end, which can only access a fastener from the top. Both ends of the wrenches have the same metric size, designed for use on a specific size fastener.
