Westward Combination Wrench 5MR44 These combination wrenches feature a 12-point box end with additional grooves that allow for easy connection with the head of the fastener and provide better accessibility at more angles, compared to a 6-point wrench. The opposite end has an open design that allows for both top and side access to the fastener, in contrast to the box end which can only access a fastener from the top. Both ends of the wrenches have the same SAE (inch) size, making them suitable for use with a specific size of a fastener.
