About Open End Wrenches

One of the most commonly used tools, open-end wrenches have one or two U-shaped heads with fixed jaws for turning or holding a specific fastener size. The jaws grip two opposing faces of a hexagonal fastener and have a smooth surface to reduce the risk of damaging the fastener. Open-end wrenches can approach a fastener from the top or side and are a useful alternative to a box wrench in applications where it is not possible to approach the fastener from the top, such as when working on pipe joints.

With a head on both ends of the tool, double-end wrenches allow a wider range of jobs to be accomplished with one tool. Each head fits a specific size of fastener. The heads may be the same or different sizes, and they may be set at the same or a different angle to the tool body.
