Kobalt 8-key Standard (SAE) Folding Hex Key Set

This SAE folding/locking hex key set contains the following sizes - 3/32, 7/64, 1/8, 9/64, 3/16, 7/32 and 1/4-in. Each hex key locks in place at 90°, 135°, and 180° to allow contact with fasteners that are in awkward-to-reach work spaces. The heavy-duty steel internal locking mechanism prevents sudden slippage and busted knuckles. The contoured body is overlaid with a thin rubber coating to allow a solid grip during use. The body is bright red so you can quickly and easily identify your SAE set of hex keys. A quick-release switch is located on each side of the case to close the corresponding tools in one simple motion. All associated hex keys fold neatly into the case for neat storage and easy transportation. Meets or exceeds ASME specifications. Hassle-free lifetime guarantee.
