Hex Keys (204 items found)

Hex keys are a common tool closely related to wrenches and sockets. They are used for turning fasteners in many kinds of DIY, maintenance, and furniture assembly projects. Our hex key range includes high-quality tools of all sizes to make fastening and loosening efficient and easy.

What's the Difference Between Hex Keys and Allen Wrenches?

Hex keys and Allen wrenches are essentially the same tools using different names. The "key" end of Allen keys or wrenches is a hexagon or six-sided shape that slots neatly into a specially designed screw or fastener. The hex key's typical "L" shape provides plenty of turning power, making tightening or loosening the fastener quicker and easier than using regular screws and screwdrivers. For particularly tight fasteners, hex keys can also be gripped with pliers to give even more traction.

However, since the tool's "L" shape can be awkward to hold at times, hex keys with handles or even combo folding sets make them easier to maneuver, particularly for smaller keys with thin stems.

Single Hex Keys or Hex Wrench Sets

Single hex wrenches are often supplied as single units in self-assembly furniture, ensuring you have the exact size you need. However, the quality of these free tools may not always be up to par. As a result, buying a dedicated tool often gives more reliable results. What’s more, hex wrench sets contain a full range of keys in standard sizes, ensuring you'll always have the right one for the job at hand.

The Main Types of Hex Keys

Most hex keys come in the classic L-shaped design, but two other common types can be more convenient, depending on the task required: T-handle and ball end wrenches.

T Handle Allen Wrench

T-handle Allen wrenches have an integrated, high-grip handle that makes them easier to use in heavy-duty situations such as auto repair and maintenance. However, while the handle adds weight and turning power, it can also make the tool harder to use in confined spaces.

Ball End Allen Wrench

A second alternative to the regular hex key is a ball end design, which, although it keeps the same overall L shape, features a rounded key end rather than a flat one. This shape makes it possible to turn the key at an angle rather than the usual 90 degrees, increasing its versatility in awkward spaces. Ball end hex keys can wear out more quickly than regular models, so they should only be used when necessary.

Reliable Hex Keys

Having quality tools you can rely on is important, from hammers to screwdrivers to hex keys. Our hex wrench sets are sourced from brands like Craftsman and Eklind, ensuring you'll have a tool you can depend on for your upcoming fastening tasks.
