Description

The Klein Tools 70591 is a folding hex key set featuring nine different SAE sizes. It includes hex key sizes of 5/64'', 3/32'', 7/64'', 1/8'', 9/64'', 5/32'', 3/16'', 7/32'', and 1/4''.

The hex ends are square-cut to ensure a secure, full-depth fit and maximum contact with the hex socket, preventing slippage and stripping. It also offers two key positions, straight-out or right angle, for added leverage.
