Boxed End Wrenches

Boxed end wrenches, known as ring spanners in the U.K., have a closed, ring-shaped end that encircles a nut or bolt, essentially "boxing" it in. The ring end features thin sides and a slightly offset head that make the wrench useful when turning fasteners in tight spaces.

Choosing a Boxed End Wrench

Box wrenches feature either 6 or 12 points inside the head. Both allow for multiple points of contact and thus a secure grip on hexagonal fasteners, though the 12-point configuration also accommodates square head bolts. With different sizes at each end, double offset box wrenches are a great value because you get two tools in one.

With a similar enclosed multi-point ring end, ratcheting box wrenches have the same advantages of a standard box wrench, with an additional ratcheting feature that allows them to tighten and loosen nuts and bolts with continuous action motion, without the user having to remove and re-adjust the wrench. All ratcheting wrenches are double ended, but the ends can either be straight or offset. Visit combination wrenches to find double-end wrenches with a box or ratcheting box-end combined with an open-end.
