Universal shelf bracket

A universal mounting bracket assembly, comprising:

• a geometrically shaped base member having a type of coupling portion, wherein the geometrically shaped base member has a front end and a rear end, the rear end being on a wall-side and the front end being opposite the rear end;
• a bore that extends through the geometrically shaped base member, in which the bore is adapted to receive a fastener that is inserted from the front end of the geometrically shaped base member and exits out the rear end to secure to a structure, the bore having a recessed area at a front portion of the geometrically shaped base member to accommodate the fastener's head;
• a geometrically shaped complementary member to the geometrically shaped base member having at its base a type of coupling portion, wherein the geometrically shaped complementary member has a greater length than the geometrically shaped base member;
• wherein the coupling portion of the geometrically shaped base member is fitted to the geometrically shaped complementary member to thereby form a single bracket assembly, in which an axial surface area is uniform;
• and
• a shelf having a hole inside which the geometrically shaped complementary member and geometrically shaped base member are inserted, and wherein the hole is on an edge of the shelf, and the shelf's edge at least partially touches the structure.
