Why Is It Called A Monkey Wrench?

The origin of the name for a common household tool may seem strange or obscure, but it has an interesting and unique story behind it. Have you ever wondered why it’s called a “monkey wrench”? In this article, we’ll explore this mysterious nomenclature and uncover the fascinating history behind this popular hand-tool.

So get ready to take a journey through time and discover why a “monkey wrench” is called what it is, and why it holds such a unique place in our world.

What is a Monkey Wrench?

A monkey wrench is a type of adjustable spanner, or wrench, which is used in mechanical and plumbing work. It is normally used when a regular spanner does not fit a particular nut separately, but instead offers an adjustable opening that can be adjusted to fit the size of the nut or bolt.

Why is it Called a Monkey Wrench?

The monkey wrench is named after Charles Moncky, an English blacksmith who invented the tool in 185

The wrench was designed to replace the thumbscrew-style spanners that had been used due to their lack of precision. Moncky wanted to create a tool that would be adjustable, yet precise enough to fit a variety of nuts and bolts, hence the adjustable jaw on the tool that is used to change its size. Moncky’s wrench was referred to as a “Moncky’s wrench” until it was popularized in the 1880s by a hardware store owner who began selling the tool.

People who had heard of the tool before this time took to calling it a “monkey wrench” due to its adjustable nature and resemblance to the arms of a monkey.


In conclusion, the monkey wrench gets its name from Charles Moncky, an English blacksmith who invented it in 185

The tool is adjustable, and thus was aptly named to reference the monkey-like arms it possesses. The tool has become ubiquitous in the plumbing and mechanical industries due to its precise nature and ability to fit a variety of nuts and bolts. Citation URL: https://en.
