An Allen wrench, also known as a hex key, is a hexagonal L-shaped wrench that is common for automotive and bicycle repairs, as well as home project use and furniture assembly. They are available individually, in sets of hex keys, or even as a multi-tool with multiple sizes of hex keys integrated into a single unit. Hex keys are available in SAE, metric, and Torx/Star in a variety of sizes and styles. It is possible to damage hex keys from over-torquing or rounding off the hex over time. If you already have the right size hex key for your repair, but it doesn't seem to fit snugly or is bent or broken, you may need to replace it to finish your repair without damaging the fastener. O'Reilly Auto Parts carries many sizes and shapes of Allen wrenches, so check out our selection to find the tools you need for your project.
