A set of metric spanners or wrenches, open at one end and box/ring at the other. These are commonly known as “combination” spanners. A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning.
An adjustable spanner (UK and most other English-speaking countries), also called a shifting spanner (Australia and New Zealand) [1] or adjustable wrench (US and Canada), [a] is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.
A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt. [2] The most prevalent form is the ratcheting socket wrench, often informally called a ratchet.

Monkey wrenches are still manufactured and are used for some heavy tasks, but they have otherwise been mostly replaced by the shifting adjustable wrench/spanner, which is much lighter and has a smaller head, allowing it to fit more easily into tight spaces, and the tooth-jawed, torque-gripping pipe wrench.
