ABSTRACT:
A T-bolt assembly having a first elongated stud with a cross bar at one end adapted to be positioned within the T-slot of a machine table and externally threaded at its other end. A second elongated stud is externally threaded at both ends while an internally threaded collar threadably engages the external threads on the first stud and one end of the second stud when the studs are axially aligned and adjacent each other. A non circular projection extends axially outwardly from one end of one stud and is received within a like shaped recess on the end of the other stud to prevent the studs from rotation relative to each other.
