摘要： A steering shaft assembly includes a shaft having a first end region including a nose, a male spline region coupleable with a female spline region of a clamp yoke, a ring flag seat adjacent said nose, and a first ring flag locating feature between said ring flag seat and said male spline region. The steering shaft assembly also includes a ring flag having an annular band seated on said ring flag seat, a flag extending axially from said annular band in a first direction beyond said first end and radially outwardly from said annular band, and a second ring flag locating feature extending axially from said annular band in a second direction opposite said first direction, said second ring flag locating feature interacting with said first ring flag locating feature to orient said ring flag in a predetermined rotational orientation relative to said shaft.

摘要： A steering shaft assembly includes a shaft having an end region to be coupled to another component with a mechanical fastener, the shaft comprising a protrusion extending radially outwardly from the shaft within the end region of the shaft. The steering shaft assembly also includes a ring flag coupleable to the end region of the shaft, the ring flag comprising a recess positioned to receive the protrusion of the shaft at a desired relative axial position of the ring flag and the shaft to rotationally align the ring flag and the shaft at a desired rotational position.
