Hex bit drivers (standard 1/4'' hex shank) are so handy for fast and efficient work that we are using them more and more, even around the house. Our set of 102 bits (slot, phillips, torx, square, and everything in between) is as great a value as is available.
Designed specifically for small scale fasteners (slot or phillips screws) and hex head bolts 3/16'', 1/4'' & 5/16'' in diameter.
