4 Interesting Facts about Hex Keys

Not everyone knows this, but there are quite a few interesting pointers related to hex keys. Let’s dive into some of them before you buy your next best hex key set.

• They Have Six Points of Contact

You might have been wondering why the tools were called “hex” keys. Well, the word hex comes from “the number 6,” if you were confused.

So, why 6? The reason why they called it a hex key is because the tool grabs the screws with 6 points of contact. This is a pretty special type of system that had been deemed quite useful back in the 1800s.

• Invented in the 1800s

If you’ve ever wondered how old these tools are, you’ll be struck with a surprise. Some of the hex keys go back to the 1800s. Yes, they are that old!

It’s not every day that you need to interact with the history of hex keys, but it’s kind of interesting. Well, obviously, they weren’t called hex keys back then. And there isn’t any solid evidence that proves that they’re this old.

But they’ve been called the Allen wrench after Mr. William Allen of the Allen Manufacturing Company. This is the company that first commercialized these little beasts and made a fortune.

• The Smallest Wrench

Another interesting fact about hex keys that you might not know is that they are the smallest of wrenches. Yep, that’s right; these little puppies can screw in the hardest of bolts regardless of their size.

A set of hex keys might weigh a lot along with the carrying case, but the form factor makes it completely worth it to work with. You can even try and fit the largest of the standard sizes into your pockets.

• They Can Fit Easily

The last fact that we’ll be talking about today is how hex keys fit seamlessly. One of the primary reasons for their use is the form factor. They can easily fit into the toughest of nooks and crannies.

Larger tools like socket wrenches and screwdrivers struggle a lot when squeezing into tight spots. But the hex keys make it look like child’s play.

I don’t know if you’ve ever noticed this, but some furniture comes with hex keys. Especially when it comes to furniture that requires assembly, you can use the small keys on the fasteners to get your job done quicker.

How to Choose The Best Hex Key Sets – Buying Guide

With the reviews out of the way, let’s look at a few factors you should consider before purchasing an Allen wrench set.

The Number of Compartments

As almost all the hex key kits in this list come with a carrying case, you need to worry about the compartment number when you’re shopping.

Some cases don’t have a lot of compartments, while others do. If you truly need that additional space, you should opt for one with more compartments.

The Design

Design is one of the things that a lot of people skip when it comes to hex keys. Some would say that the ball end Allen wrenches have the best design, while others would disagree.

Size

Another thing to consider before going out to purchase a set of hex keys is the size. All of them come in different sizes but it’s you who needs to choose which size suits you best. If you want something compact, check out the foldable options.

Portability

When you’re working as a professional in the mechanical or automobile industry, you’ve got to keep the portability factor in mind.

Most of the sets on our list come with a carrying case. Whether they’re made of wood, plastic, or even leather, they serve the same purpose. And that’s to make them portable. So, pick one that you’ll be able to carry easily from one place to another.

Construction

Stainless steel is something that is common in these Allen wrenches. All the best hex wrench sets have a durable build.

You can either get chromium-vanadium steel or Protanium steel from them. But you can’t see the steel due to the black oxide coating most of the time.

Price Range

The prices of hex keys from different brands vary quite a lot. And the more well-known brands charge extra just for the brand value that they’ve created.

So, pick wisely and see if it suits your budget. You can get most of these for around $15, while the premium ones will set you back over a hundred bucks.

Warranty Offer

This is also another factor to take into account when you’re on the hunt for a new complete Allen wrench set. Normally, you shouldn’t opt for a set that doesn’t come with a warranty.

It’s important that you take a hex key set that offers at least a one year warranty. You never know when a grip might fall off, or the entire wrench might break.

So, it’s essential to keep this in mind when you’re buying. But that doesn’t mean that a set without a warranty is bound to break. These things can give you over five years of service if you’re careful.

FAQs on Allen Wrench Sets

1. What is an Allen Wrench, actually?
