What is an adjustable wrench?

An adjustable wrench also goes by the name of an adjustable spanner and adjustable crescent wrench. But, all the names refer to one type of tool.

A wrench is used to tighten nuts and bolts. It is easy to tighten nuts and bolts with a wrench because it has jaws that are adjustable in size, so they offer the perfect grip.

For that reason, you can easily maneuver the wrench and tighten or loosen what you need quickly. An adjustable wrench is especially useful for working with tubes, pipes, nuts, and bolts.

How many types of adjustable wrenches are there?

There are four types of adjustable wrenches which have their own distinctive uses and characteristics. The most common is the crescent wrench, also known as a “crowfoot” or adjustable spanner for its varied use in loosening bolts. Then there are the Monkey Wrench, Pipe Wrench, and Plumber Wrench.

Adjustable Spanners


Also called crescent wrenches, adjustable spanners are available in virtually every household these days.

With this type of wrench you can apply increasing torque to move tightened fasteners by using your hand’s natural grip motion.

The most distinct characteristic of the adjustable spanner is the 15° angle between the handle and the movable jaw.

Adjustable spanners are reasonably priced, and apart from that, they come in a broad range of sizes to suit any job you might have in mind.

They are best suited for unscrewing or fastening plumbing fixtures like elbows, faucets, and pipes.

If you don’t have enough strength to open bottle lids? There’s an adjustable spanner subtype that is meant just for you.

As you use the adjustable spanner, ensure that the movable jaw is clasped securely around the pipe. This will help prevent rounding, which can be a pretty annoying issue.

Also, be sure to position the jaw on the side toward which the rotations will happen. This will help avoid deforming the wrench. As well, this ensures a tighter grip as you start to move the wrench around.

Adjustable spanners vs crescent wrench

The adjustable spanner or wrench has been around for a long time. In the U.S., Canada, and other countries it’s known as “Crescent wrenches” due to their popularity in these regions from the original patent holder of Crescent Tool Company which was founded back in 1887.

Monkey Wrench


Looking for an adjustable wrench to use in large-scale projects like fixing vehicles or water systems for customers in your neighborhood? Then, you will need a monkey wrench.

What most distinguishes this adjustable wrench is its long handle and sharp jaws that grip objects very firmly.

The tool is crafted from steel or its alloys through a process known as heat-forging.

In most cases, the monkey wrench is used to clamp onto pipes, lug nuts, screws, and bolts.

The sturdy construction is what accounts for the monkey wrench’s remarkable strength. A monkey wrench is capable of bearing your entire weight as you push against it.

Pipe Wrench

Pipe-WrenchPeople often confuse the pipe wrench with the monkey wrench, as the two are very similar. Nonetheless, the pipe wrench, otherwise known as the Stillson wrench, happens to be sleeker than the monkey wrench.

Moreover, this wrench makes it easier for you to reach difficult locations like corners and nooks.

The pipe wrench is perfect when you’re working with round-surface fixtures and soft iron pipes. But, you shouldn’t use it with hex nuts as its teeth can quickly ruin the hex head.

The Stillson wrench is manufactured from steel or aluminum and can be bought in different handle sizes, including 10”, 18”, 24”, 36”, and 48”.

There are also jaw kits if you prefer repairing your old pipe wrench rather than purchasing a new one.

What is the difference between a monkey wrench and a pipe wrench?

A monkey wrench is a type of wrench that is not as popular as a common pipe wrench. It is only used for hex nuts, thus it has limited usability. The monkey wrench has serrated jaws that offer excellent grip and therefore, it is easy to use.

On the other hand, a pipe wrench is made to twist pipes, and it is mostly used by plumbers. Metal pipes require manual twisting and that’s when the pipe wrench (like some of these) comes in handy.

The most obvious difference between the two types of wrenches is that the monkey wrench has jaws that are straight out. In contrast, a pipe wrench has slightly curved jaws. These provide a better grip when used on round objects.

Plumber Wrench

Plumber-WrenchPlumber wrenches come with a key ring fitted to one handle, for closing the movable jaws around the fitting or pipe. Plumbers use this type of wrench to rotate the plumbing pipes.

This wrench clasps with striking force, and hence it doesn’t need to engage the bolt or nut head it’s applied to.

As the wrench is quite bulky, you should only use it where other kinds of wrenches don’t work.

When used carelessly, this type of adjustable wrench can cause dents or even break a pipe.

What to look for when buying an adjustable wrench

Ok, so you are on the market for an adjustable wrench. Here’s what you should consider when choosing one. First of all, keep in mind that one good adjustable wrench replaces several different types of wrenches.

  • look for a wrench made of industrial-grade alloy
  • check that the wrench has a comfortable plastic grip that is non-slip
  • the scales should be easy to see and clearly marked so that you can set the specific nut sized quickly
  • make sure it is easy to adjust
  • the wrench should have a hole in the handle so that you can hang it up

Despite being a pro, a resourceful buying guide can surely help you to know the known and unknown facts about any tool. And if you’re a noob, you must keep track of the specifications of the tool for better workability. Let’s get acquainted.


Comfort Grip

Unlike favorites, and comfort in grip is the feature that particularly depends on your personal preferences according to your comfort. But no matter what kind of wrench you buy, make sure the handle of the tool is grooved so it doesn’t slip away from your hand while you are working on a lug nut.

A metal handle will give you more durability while the comfort grip will be convenient to use for a long time. If your hand is wet or you sweat more, you won’t be able to work with the metal grip. On the other hand, light but bulky grip will affect the actual capacity of the wrench. We recommend the latter.


When you go to search for a wrench, you will find some wrenches have scales etched on their jaws. The scales that can be found are on metric and SAE or inch systems. Some wrenches have both types of scale, some got any of the ones, and some don’t have at all.

The scales are provided so that you can quickly measure the fasteners’ dimensions for better workability or different purposes. So it’s better to buy an adjustable wrench with both scales etched on the jaws.

Wrench Kit

In this tale of pursuit,  many adjustable wrenches are ready to sell. You’re gonna see some manufacturers offering wrenches of different sizes, but you need to buy them separately. But some manufacturer provides a wrench set or kit that offers you two or more wrenches at the same time at less price than the price when you buy all the wrenches individually.

You should go for one of the wrench sets for better workability as you often need to use this tool with many types of fasteners.

Jaw Capacity

Jaw capacity reflects how bigger the fastener the wrench can hold onto. The more the jaw capacity, the bigger fasteners it can hold and measure. Both horizontal and vertical surfaces play a fundamental role.

The capacity of the jaws vary from wrenches to wrenches, the capacity can be as small as only ½ inch to as big as 3 inch or more. Irrespective of your choice, you should confirm that the length and the weight of the wrenches are well proportioned. Otherwise, the wrench will break or it will be so hard to work with.


Product quality is the most important feature no matter what you buy. And the quality mostly depends on the material used to build the product. In the case of adjustable wrenches, always prefer a wrench made of high-quality steel since only a durable tool is worth your money.

In the market you will find wrenches made of alloy steel, they are robust and extremely hard to break. But wrenches made of chromium-vanadium are even stronger. You should also keep in mind that the coating materials make tools more durable. Without the coating, your steel won’t be able to prevent rust and corrosion. For lifetime corrosion-resistant, chrome or nickel coating is the best.


Since loosening and tightening fasteners like nuts and bolts are the main purposes of an adjustable wrench, it must be a portable tool. Though the portability depends on the weight of the item, a heavy portable tool is not as comfy as a lightweight tool.

A lighter tool is really easy to use but you can’t just go and pick the lightest tool. The lighter weight of a wrench means it has less metal mass than a heavy one. And that won’t offer you much workability.


Lengths of the wrenches usually vary from 4 inches to 24 inches in today’s market. You should always select a wrench with the proper length you need for your work, as torque and workability of the wrenches depend on the length of the tool. The more the length of a wrench, the more torque it produces. Every time consider buying a longer wrench for heavier work. Also, longer handles help you to reach far places. But for small and tight areas, smaller wrenches are the compatible ones.


As the purpose of instruction is to let you know how to install and use any tool, you can name it as a guidebook. You might think that you don’t need any instruction for a simple tool like an adjustable wrench.

Your guess is right but you need to keep in mind that not all the providers provide the same kind of tools and to improve the workability they change their wrenches accordingly. Also, you may damage the device you’re working on if you don’t know the proper use of a wrench.

For this reason, you better keep instruction at your arms reach. It can help your kid or someone who doesn’t know how to use the wrench.


Neither all manufacturers on the market provide you with a warranty nor is the period of the guarantee the same. Some providers offer a warranty for every item they sell, some only do for specific items while some don’t provide a warranty at all. At the same time, the period of the guarantee varies from provider to provider.

Especially it’s better to go for the product with the lifetime warranty. It proves their confidence on the wrench they’re providing.
