Claim 3

A wrench socket assembly in combination with a threaded fastening member adapted to be received within and turned by said assembly, said assembly comprising a body having a central axis, a socket formed in said body along said axis, a side wall defining the periphery of said socket within said body and extending in a generally axial direction, an end wall of said socket formed integrally with said side wall and extending in a generally radial direction from said side wall toward the axis of said body, said side wall comprising a series of alternating protrusions and recesses respectively extending toward and away from the axis of said body in a generally radial direction so as to mate with said fastening member with a driving fit, a hole formed in said end wall, an insert member mounted within said hole and extending into said socket, means connecting said insert member with said fastening member to keep said body from wobbling on said fastening member while still permitting relative rotation between said insert member and said fastening member, said means including an opening of predetermined width formed in one of said members, and a projection having a width slightly smaller than said predetermined width and being formed on the other one of said members so as to mate with said opening when said fastening member is inserted into said socket.

Claim 4

A wrench socket assembly in combination with a threaded fastening member adapted to be received within and turned by said assembly, said assembly comprising a body having a central axis, a socket formed in said body along said axis, a side wall defining the periphery of said socket within said body and extending in a generally axial direction, an end wall of said socket formed integrally with said side wall and extending in a generally radial direction from said side wall toward the axis of said body, said side wall comprising a series of alternating protrusions and recesses respectively extending toward and away from the axis of said body in a generally radial direction so as to mate with said fastening member with a driving fit, a hole formed in said end wall, an insert member mounted within said hole and extending into said socket, means connecting said insert member with said fastening member to keep said body from wobbling on said fastening member while still permitting relative rotation between said insert member and said fastening member, said means including an opening of predetermined width formed in one of said members, and a projection having a width slightly smaller than said predetermined width and being formed on the other one of said members so as to mate with said opening when said fastening member is inserted into said socket.

Claim 5

The combination therefor defined by claim 1 wherein said hole is generally circular in shape having a predetermined diameter, said insert member comprising a generally cylindrical head having a diameter substantially equal to said predetermined diameter of said hole to telescope within said hole with a press fit, a circular base projecting radially outwardly from one end of said head and having an upper side engaging said end wall of said socket.

Claim 6

The combination therefor defined by claim 2 wherein said opening is generally circular in shape, said projection being generally cylindrical in shape.

Claim 7

The combination therefor defined by claim 3 with said projection being formed integrally with said insert and extending in an axial direction from the lower side of said base opposite said head.

Claim 8

The combination therefor defined by claim 3 with said opening being formed in the lower side of said base opposite said head.

Claim 9

The combination therefor defined by claim 5 with said insert member including an annular boss projecting axially from said base in a direction opposite said head, said opening extending upwardly through said boss and into said base, said fastening member including an upper end portion adapted to be received within said socket, a central depression formed in the top of said upper end portion, said projection extending upwardly from the center of said depression.

Claim 10

The combination therefor defined by claim 3 with said side wall defining said socket being generally cylindrical in shape and including twelve of said protrusions and twelve of said recesses, each of said protrusions having a convex surface curving toward the axis of said body, each of said recesses having a concave surface curving away from the axis of said body.

Claim 11

The combination therefor defined by claim 7 wherein the diameter of the socket as measured between said recesses is approximately ten-percent greater than the diameter of the socket as measured between said protrusions, the radius of curvature of each of the protrusions being approximately twice that of the radius of curvature of each of said recesses.

Claim 12

A wrench socket assembly adapted to receive a threaded fastening member having a head with an upwardly extending cylindrical projection of predetermined diameter said assembly being adapted to turn said fastening member and comprising a body having a central axis, a socket formed in said body along said axis, a side wall defining the periphery of said socket within said body and extending in a generally axial direction, an end wall of said socket formed integrally with said side wall and extending in a generally radial direction from said side wall toward the axis of said body, said side wall comprising a series of alternating protrusions and recesses respectively extending toward and away from the axis of said body in a generally radial direction so as to mate with said fastening member with a driving fit, said side wall defining said socket as being generally cylindrical in shape, each of said protrusions having a convex surface curving toward the axis of said body, each of said recesses having a concave surface curving away from the axis of said body, the diameter of the socket as measured between said recesses being approximately ten percent greater than the diameter of the socket as measured between said protrusions and the radius of curvature of each protrusion being approximately twice that of the radius of curvature of each of said recesses, a circular hole formed in said end wall, an insert member mounted within said hole with a press fit and extending into said socket, and a circular opening formed in the lower end of said insert member and having a diameter slightly larger than said predetermined diameter so as to mate with said projection when said fastening member is inserted into said socket thereby to keep said body from wobbling on said fastening member as the latter is being turned.

Claim 13

A wrench socket assembly adapted to receive a threaded fastening member having a head with an upwardly extending cylindrical projection of predetermined diameter said assembly being adapted to turn said fastening member and comprising a body having a central axis, a socket formed in said body along said axis, a side wall defining the periphery of said socket within said body and extending in a generally axial direction, an end wall of said socket formed integrally with said side wall and extending in a generally radial direction from said side wall toward the axis of said body, said side wall comprising a series of alternating protrusions and recesses respectively extending toward and away from the axis of said body in a generally radial direction so as to mate with said fastening member with a driving fit, said side wall defining said socket as being generally cylindrical in shape, each of said protrusions having a convex surface curving toward the axis of said body, each of said recesses having a concave surface curving away from the axis of said body, the diameter of the socket as measured between said recesses being approximately ten percent greater than the diameter of the socket as measured between said protrusions and the radius of curvature of each protrusion being approximately twice that of the radius of curvature of each of said recesses, a circular hole formed in said end wall, an insert member mounted within said hole with a press fit and extending into said socket, and a circular opening formed in the lower end of said insert member and having a diameter slightly larger than said predetermined diameter so as to mate with said projection when said fastening member is inserted into said socket thereby to keep said body from wobbling on said fastening member as the latter is being turned.
