Open End Wrench

Open end wrenches are a type of nonpowered, nonedged hand tool that falls under the supply class of Nonpowered Nonedged Hand Tools in the supply group Hand Tools.

Open end wrenches are designed with two open jaws or ends, each with a fixed size. These jaws are typically in the shape of a U or C, allowing them to fit over the nuts or bolts of various sizes. The open end wrench is used to tighten or loosen nuts and bolts by applying torque to them.

One advantage of open end wrenches is that they can be used in tight spaces where other tools may not fit. However, they have limited contact with the fastener, which can increase the risk of slipping or rounding off the edges of the nut or bolt.

Open end wrenches are available in different sizes to accommodate various nut and bolt sizes. It is important to use the correct size wrench to ensure a proper fit and prevent damage to the fastener.

Overall, open end wrenches are a versatile and commonly used hand tool in various industries, including automotive, construction, and maintenance.
