The Klein Tools 823910 is an 8-key SAE folding hex key set that keeps all your most-used inch sizes organized in a single compact, fold-out handle. Sizes included are .050, 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", and 5/32" — covering a wide range of fastener applications in electrical, mechanical, and general maintenance work.
The folding design protects the keys when not in use and allows one-handed selection on the job. At just 3-1/16" overall, this set slips easily into a tool bag or pocket, while individual key lengths ranging from 1-1/2" to 2-3/8" provide the reach needed for recessed fasteners.
