Patent ID: 8840349

Claim:
An adjusting screw, comprising: a cylindrical body having a first end, a second end, and an outer curved surface; a first raised portion on the first end and offset from a longitudinal axis of the cylindrical body, the first raised portion to engage a first hexagonal-shaped socket to turn the cylindrical body about the longitudinal axis, the first raised portion having first peripheral outer surfaces to engage less than all faces of the first hexagonal-shaped socket, wherein at least two adjacent ones of the first peripheral outer surfaces are to be substantially parallel to two respective adjacent faces of the first hexagonal-shaped socket; and a second raised portion on the first end and offset from the longitudinal axis of the cylindrical body and opposing the first raised portion, the second raised portion having second peripheral outer surfaces to engage the first hexagonal-shaped socket to turn the cylindrical body about the longitudinal axis, wherein the outer surfaces of the second raised portion engage less than all of the faces of the first hexagonal-shaped socket, wherein at least two adjacent ones of the second peripheral outer surfaces are to be substantially parallel to two respective adjacent faces of the first hexagonal-shaped socket and wherein the at least two adjacent ones of the first and second peripheral outer surfaces are to engage less than all faces of a second hexagonal-shaped socket to turn the cylindrical body about the longitudinal axis, wherein the first hexagonal-shaped socket is smaller than the second hexagonal-shaped socket.
