This is because there are dozens of different types of wrenches, from basic wrenches like adjustable wrenches, which can be used for a nearly endless list of tasks, to specialty wrenches like basin wrenches, which are purely for replacing faucets under tight sink basins.

Best for: Quickly changing wrench sizes without changing tools

Dog bone wrenches have nothing to do with dogs. They get their name from their resemblance to a stereotypical dog bone shape, as they have a skinny handle between two bulky ends. The ends feature multiple wrench sizes that allow the user to quickly undo fasteners without having to grab another tool or adjust a tool to fit.

Choosing the Right Wrenches for Your Toolbox

Whether you choose to outfit your toolbox with every wrench or you opt for a key few, this list of essential wrenches is sure to get you started. While some homeowners will indeed find a use for every single wrench listed, others will benefit from a set of sockets and a ratcheting handle, combination wrenches, hex keys, an adjustable wrench, and possibly a pipe wrench.
