Socket wrench extension with improved torque transmission

A socket wrench extension for engagement with a socket and a socket wrench comprising:

• a. a main body having
• a first end defining a cavity having a square cross-section and adapted to receive a portion of the socket wrench,
• an opposite second end, and
• an axis that extends through said first and said second ends;
• b. a drive column proximate said main body second end, wherein said drive column is adapted to be received in a square cavity formed in one end of the socket and defining a longitudinal axis that is coincident with said main body axis;
• c. a concave recess formed in said drive column;
• and
• d. a shoulder formed intermediate said main body second end and said drive column annular recess, said shoulder having a cross section that is larger than a cross section of said drive column recess and smaller than a cross section of said main body, wherein each of said cross sections are taken perpendicular to said main body axis, and
• wherein said drive column is receivable in the square cavity formed in the socket in
• a first position in which said drive column axis intersects an axis of the socket at a non-zero angle, and
• a second position in which said drive column axis is coincident with the axis of the socket and said shoulder is matingly received in the square cavity of the socket.

A socket wrench extension and a socket comprising:

• a. a socket defining a cavity having a square cross-section therein and a second end adapted to engage a fastener;
• and
• b. a socket wrench extension having
• i. a main body that has
• a first end defining a cavity having a square cross-section and adapted to receive a portion of a socket wrench,
• an opposite second end, and
• a longitudinal axis that extends through said first and said second ends;
• ii. a drive column proximate said main body second end, wherein said drive column is adapted to be received in said socket first end square cavity, said drive column having a longitudinal axis that is coincident with said main body axis;
• iii. a concave recess formed in said drive column;
• and
• iv. a shoulder formed intermediate said main body second end and said drive column annular recess, said shoulder having a cross section that is larger than a cross section of said drive column recess and smaller than a cross section of said main body, wherein each of said cross sections are taken perpendicular to said main body axis, and
• wherein said drive column is receivable in said socket first end cavity in
• a first position in which said drive column axis intersects an axis of said socket at a non-zero angle, and
• a second position in which said drive column axis is coincident with said socket axis and said shoulder is matingly received in said socket first end square cavity so that said socket first end abuts said main body second end.

• wherein said main body is longer than said drive column, and
• wherein said drive column is receivable in said socket first end square cavity in
• a first position in which said drive column axis intersects an axis of said socket at a non-zero angle, and
• a second position in which said drive column axis is coincident with said socket axis and said shoulder is matingly received in said socket first end square cavity so that said socket first end abuts said main body second end.

• c. a concave recess formed in said drive column that bisects said drive column into a first part distal from said main body second end and a second part proximate said main body second end;
• and
• wherein said drive column is receivable in the square cavity formed in the socket in
• a first position in which said drive column first part is within said drive socket square cavity and said drive column second part is not so that said axis of said drive column intersects an axis of the socket at a non-zero angle, and
• a second position in which both said first and said second drive column parts are received in said socket square cavity and said drive column axis is coincident with the axis of the socket.
