The Klein Tools 5-Key Folding Hex Key Set is a compact and durable solution for tightening and loosening hex fasteners in field, shop, or maintenance settings. Designed with five SAE sizes, this folding set fits easily into a pocket or tool box, helping eliminate the risk of lost keys. The square-cut hex ends provide full-depth engagement with hex sockets, reducing slippage and socket stripping during use. Ideal for mechanical, electrical, and general-purpose applications, this tool supports efficient work in tight or mobile environments.

Built from alloy steel with a satin finish, the hex keys offer two working positions—straight-out or right angle—for added leverage and control. Precision-chamfered ends eliminate burr-related issues, while the flat-end design ensures consistent contact. The folding handle provides quick access to each key and keeps them securely housed when not in use. This tool is not insulated and should not be used near live electrical circuits.
