If you have recently assembled a piece of furniture, you probably had to dig in your toolbox for a hex wrench. Hex wrenches get called many names —  hex keys, hex-key wrenches, Allen keys and Allen wrenches —  and are widely used to work with products requiring assembly. Tasks include assembling wooden and metal furniture, adjusting the height of bicycle seats, even tightening screws in car engines might need the help of a hex wrench. You can use them to drive, fasten, or loosen screws that have hexagonal socket heads or screws with a six-sided head. 


Hex Wrench vs. Allen Wrench: What’s the Difference?

You may have heard people refer to hex wrenches as Allen keys or Allen wrenches and wonder if there’s any difference between them. Well, no. There isn’t. A hex wrench and an Allen wrench are essentially the same tools, except that the latter got its name from Allen Manufacturing Company since founder W.G. Allen patented the design in 1909 for the screw requiring the original hex wrench shape.  


Selecting the Best Hex Wrench for the Task

The vast majority of hex wrenches are available as wrench sets. These are practical and handy since they come with a wide variety of the most used wrench sizes. 

There are three standard shape options for a hex wrench set: L-Shape, T-Shape, or folding — more on what these choices mean below. Another characteristic to note is how they are measured. These sets come in the Society of Automotive Engineers (SAE) standard sizes — fractions of an inch — or imperial sizes, another name for metric, which uses millimeters. Typical kits include SAE or metric sizes, so if you need to use a specific screw size wrench, pay attention to that. Some kits offer both, which may be the best bet if you work across different types of projects.

  • L-Shape: This type of hex wrench is most common, and the one with which most are of us are familiar. 
  • T-Shape: The T-shape hex wrench works best in hard-to-reach areas that require more torque. The top of the tool acts as the handle, while the extension is the hex wrench. The handles of some T-shaped hex wrench designs also include an Allen wrench or hex wrench.  
  • Folding Kit: We consider these hex wrench kits the most versatile. You can use them in either an L- or T-shape, depending on your specific needs at the time. 

Now let’s jump into the best hex wrench kits to get your furniture assembled or other projects in order in no time.
