1. A self-adjusting deep well socket comprising:
a case insert having a tool receiver end sized and shaped to receive a drive square of a socket wrench, an opposed fastener receiver end sized and shaped to receive a threaded fastener having a height measurement and an outside diameter measurement, and a deep well chamber extending from the tool receiver end to the opposed fastener receiving end;
a case body having a top end, a bottom end, and an interior wall defining a cavity extending from the top end to the bottom end, the cavity sized and shaped to receive the case insert such that the tool receiver end is positioned at the top end of the case body and in which the case body and the case insert have a coaxial relationship; and
a plurality of fingers in an annular array inside the case insert at the fastener receiving end;
wherein the case insert and an interior wall of the case body are both formed with complementary mating threads;
wherein each finger has a pivoting end around which the finger pivots about an attachment point at an upper end of the annular array;
wherein the plurality of fingers move into the deep well chamber when the case insert is rotated in a first direction towards the fastener receiving end;
wherein the cavity is further sized and shaped to accommodate a travel distance of the case insert rotating within the case body;
wherein the plurality of fingers of the case insert are at all times housed within the case body regardless of the travel distance; and
wherein the deep well chamber is sized to internally accommodate the height measurement of the fastener, where the height measurement is at least 2 inches.
