What is the difference between a spanner and a wrench?
Wrench
Confusion can arise between spanners and wrenches, mainly because of the confusion that occurs whenever you refer to the tool anywhere in the world.
In short, the US and UK use the two tool names differently, which means they are used interchangeably and often incorrectly.
In the US, both fixed and adjustable tools are called spanners.
However, in the UK, fixed tools (of a specific size) are called spanners and adjustable tools are called spanners.
What is a spanner?
Two spanners in your pocket
Wrenches (which can be called fixed tools) are used to turn nuts and bolts, loosening or tightening them. Wrenches are often used for work that requires precision or in areas where space is restricted.
There are three common types of spanners, including:
Open-end spanners – These are open tools with a "U" shape at both ends. Open-end spanners can also be called double-ended spanners. This is a sturdy yet lightweight option if your job requires you to work for long periods of time.
Socket wrenches - Great for hard to reach places, socket wrenches (also known as "tubular wrenches")
Combination wrenches - These are double-ended tools that are open on one end and ring-shaped on the other. This design helps it perform the functions of two wrenches.

Pipe wrenches
Wrenches (also known as adjustable tools) usually have a removable lower jaw that allows you to adjust the tool to the size of the bolt or nut. Due to their adjustable nature, spanners are much bulkier than wrenches.
There are many types of wrenches, some of which are:
Pipe wrenches - This tool is used to turn pipes or round rods. This pipe wrench is available in a variety of sizes, starting at 35mm and going up to 78mm.
Pin hook wrenches - This type of wrench is used to remove rings, ferrules, and lock nuts.
Torque wrenches - Mechanics usually use this type of tool for specific jobs, such as changing tires, and it is usually paired with a socket.
What are spanners and wrenches used for?
Wrenches on car engines
As mentioned before, wrenches are fairly bulky tools, which makes them difficult to use in tight or confined spaces. However, the adjustable nature of wrenches allows them to be used for a variety of jobs that require a variety of different sized nuts and bolts.
If you are planning on doing a job that requires precision, then a wrench will be the right tool. The head of a wrench tends to be thinner than a spanner, making it easier to fit into tight spaces.
In addition, since wrenches are size-specific (which means you can choose the right size wrench for the job), there is less chance of rounded corners.
Wrenches are not only ideal for home improvements, but any other job that requires precision, especially when space is limited. For example, wrenches are often used in the automotive industry.
We hope that you understand the difference between a wrench and a spanner, and what you need when performing a specific job.
