The Klein Tools 9-Key Folding Hex Set is a compact and durable solution for professionals who need quick access to multiple hex sizes in the field or workshop. Designed for secure fastening and loosening of hex bolts, this tool includes nine SAE-sized keys housed in a folding handle that fits easily into a pocket or tool box. The square-cut hex ends provide full-depth engagement with hex sockets, reducing the risk of slippage and socket stripping during use. Ideal for maintenance technicians, electricians, and mechanical trades, this set 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. The folding design eliminates the need to carry loose keys and helps prevent loss. Each key is precision-sized for consistent performance across a range of applications, including equipment assembly, field repairs, and general mechanical tasks.
