The innovative MagicSpring® is a steel retaining ring on the long tip, which grips the recess in the head of the screw. This allows easier insertion into or removal from deep counter-bored holes and generally hard-to-reach spots. The hex key in effect becomes a handle with the screw held securely on its tip. The holder keeps the keys firmly in place until required, even when stored vertically by the hanging hole. The 7-piece Torx set covers the size range from T6 to T20.
