Westward 5MR69 Combination Wrench These combination wrenches feature a 12-point box end with additional grooves, making it easier to connect with the fastener head at various angles. This design provides better accessibility compared to a 6-point wrench. On the opposite side, there is an open-end design that allows both top and side access to the fastener, unlike the box end, which only allows top access. Both ends of the wrench have the same SAE (inch) size, allowing them to be used on a specific size fastener.
