Just in Case
TEKTON Hex Key Wrench Set, 30-Piece (.028-3/8 in, 7-10 mm)
This 30-piece set of hex key wrenches come neatly tucked in a bright red storage case so you'll always be able to find it in a flash. It opens flat so you can see all of the wrenches — and their sizes — at a glance, and remove them easily as needed. Each wrench boasts chamfered (or slightly-sloped) edges to provide a snug fit while preventing damage to your screws and fasteners. They all have a long arm/short arm design to give you options depending on the amount of space you have to work and how much leverage you need to get the job done. Each also features a black oxide finish that resists corrosion and will not chip, so you can depend on these in the long-term.

Amazon customer dviper1712 says: “I have been using these on the job now for 5 years. They pretty much see daily use in an industrial environment. They have been dropped, over torqued, abused and soaked in hydraulic oil. They still perform like new. Even the letters and numbers on the holder are still visible!”
Inch-by-Inch, Meter-by-Meter
TEKTON Long Arm Ball End Hex Key Wrench Set, Inch,13-Piece
Each wrench in this set features a long arm/short arm design that allows for extra reach or extra leverage as needed.

Each wrench is finished with black oxide to resist corrosion and eliminate chipping even when used under high stress, and they all fit neatly in the included storage case that opens flat for easy access.
Two separate sets are available — one with inch measurements and one with metric measurements — so be sure to pick the option that is best for your needs.

All-in-One
Park Tool AWS-10 Fold-Up Hex Wrench Set
This stand-out tool is perfect for taking your allen wrenches on-the-go.

With hex keys ranging from 1.5mm to 6mm, it's a particularly great option for bicycle upkeep. Just flip out the wrench you need and take grip of the lightweight, slip-resistant handle. The wrenches themselves are made from hardened industrial tool steel — 40 percent stronger than standard steel handles — and their chamfered tips ensure a perfect fit without stripping fasteners.
