Innovative, extremely compact quadruple bit for hexagonal socket screws in sizes 3.0, 4.0, 5.0, and 6.0. This bit is tough for hard materials and features a 1/4" hexagon drive (Wera connecting series 1). It offers significant weight savings of over 50% and allows for the operability of larger profiles through spring compression of smaller tips. It can be used with bit ratchets and bit-holding screwdrivers.
