View On Amazon View On Home Depot View On Walmart

This sturdy set of Allen wrenches from Tekton includes the full range of commonly used sizes for both metric and SAE. Made of steel with a black oxide finish, the wrenches will hold up to rigorous use without damage, and they won't slip even when you need to apply a fair amount of torque to turn a tight screw. The ends of both the short and long sides are chamfered for the most precise fit, so you won't struggle to fit the wrench into the screw socket.

The set includes metric sizes 0.7, 0.9, 1.3, 1.5, 2, 2.5, 3, 4, 4.5, 5, 5.5, 6, 7, 8, and 10 mm. The SAE sizes are 0.028, 0.035, 0.050, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, and 3/8 inch. The smallest sizes are not marked, but the larger wrenches have their sizes clearly marked on the tools, making it easier to find the one you need. The SAE wrenches are longer than the metric wrenches, which also helps differentiate among them. As with most hex wrench sets, the larger sizes are longer than the smaller sizes, which gives you a better grip when applying more force to turn larger screws.

The set comes with a plastic storage case that opens flat for easy access to the wrenches. The case is clearly marked with each wrench size, further helping you to quickly find the tool you need. Whether for around-the-house use, assembling furniture, working on the car, or even professional use, you are unlikely to need a hex wrench that isn't included in this 30-piece set.

Best Foldable

Texas Best Folding Hex Key Set

View On Amazon

A folding set of hex wrenches can be very convenient, especially if you need a variety of sizes throughout your project. This set of steel folding hex wrenches from Texas Best includes two separate tools: One yellow set of metric wrenches in sizes 1.5mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm, and 8.0mm, and one red set of SAE wrenches in sizes 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, and 1/4 inch. All of the wrenches have their size clearly marked on the tool handle and pull out easily for use.

As with any set of folding Allen wrenches, it can be trickier to use these in tight or awkward spots, as the handle of the tool can get in the way of your reach, and the wrenches themselves are not as long as the typical individual wrench. Still, these are undeniably handy for most common DIY projects, such as assembling furniture or tightening loose screws on chairs, tables, and other household objects. Plus, it's very easy to store these in a drawer or your tool box.

Best for Around the House

Amazon Basics 26-Piece Hex Key Set

View On Amazon

Made of chrome-vanadium steel with a black oxide finish, this set of 26 hex keys in all the common metric and SAE sizes is perfect for those around-the-house projects, such as assembling flat-packed furniture, tightening loose hexagonal screws on furnishings, working on cars or motorcycles, or repairing large appliances. These Allen wrenches have ball ends on the long side, which allows you to turn the screw with the wrench at a slight angle, rather than the upright position required by straight-end hex wrenches. This makes it much easier to access screws in awkward or difficult-to-access spots.

The set includes metric sizes 1.27, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 8, and 10 mm. The SAE sizes include 0.05, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, and 3/8 inch. Each set has a hinged plastic holder with clearly marked sizes to keep your hex wrenches neatly stored and to make it easy to find the size you need. This reasonably priced set of Allen wrenches is a worthy addition to your home tool collection.

LEXIVON Master Wrench Key Set

View On Amazon View On Walmart View On Lexivon.com

Made of industrial-grade alloy steel with a manganese phosphate coating, this set of professional-quality hex wrenches includes metric, SAE, and Torx (star) sizes. Torx screws, which have star-shaped sockets on their heads, rather than the hexagonal sockets found on other hex screws, are commonly used in many types of vehicles, including cars and motorcycles. They are also often used for consumer electronics, such as laptops and computer components. All of the included hex wrenches are chamfered on the short end for extra precision and have a ball end on the long side of the tool, which allows you to hold the wrench at up to a 25-degree angle when accessing an awkwardly placed fastener.

The 13 included metric sizes are 1.27, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 8, and 10 mm. The 13 included SAE sizes are 0.05, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, and 3/8 inch. There are nine Torx wrenches in sizes T10, T15, T20, T25, T27, T30, T40, T45, and T50. Every wrench has its size clearly laser-etched on the center of the tool. Each of the three types of wrenches has its own hinged storage case, which is also clearly marked with the wrench sizes.

Best T-Handle

Craftsman T-Handle 14-Piece Hex Key Set

View On Amazon View On Walmart View On Lowe's

T-handled hex keys allow you to apply quite a bit more force when turning tight screws, and are also a little longer than regular hex wrenches, which is useful when accessing deep or awkward fasteners. This type of handle is a popular option for carpentry, plumbing, mechanical, and electrical work, as well as large DIY projects. This set of 14 black-oxide-coated steel hex wrenches includes metric sizes 2.5, 3, 4, 5, 6, 8 and 10 mm and SAE sizes 3/32, 7/64, 1/8, 5/32, 3/16, 7/32 and 1/4 inch. All are easy to use, thanks to their comfort-grip handles.

Each wrench has its size printed on the handle. The two storage cases keep your Allen wrenches neatly organized, but on the downside, they do not have sizes marked at each tool's slot. Still, it's easy to read the sizes on the wrench handles, so it's not a chore to quickly select the size you need. While somewhat more expensive than L-shaped hex wrenches, this is a great set if your work or hobbies require regular turning of hex screws.
