Striking box wrench 12-points

Striking box-end wrenches have an offset handle that allows access to fasteners in tight spaces. A block shape on one end of the handle is struck with a hammer to loosen or tighten a fastener. The striking wrench is a standard tool, used in all kinds of conditions, in the predominantly heavy industry intended to loosen or fix bolts and nuts. A big disadvantage of this type of wrench is the fact that you must hold the striking wrench with one hand, while you operate the hammer with the other hand.
