Steering shaft assembly

A shaft assembly, comprising:

• a yoke having a yoke body having an exterior surface extending between a first end and a second end along a first axis, the yoke body defining:
• a first bore that extends along the first axis between the first end and the second end, and
• a second bore that extends partially across the yoke body along a second axis that is disposed transverse to the first axis, the second bore at least partially intersects the first bore,
• a shaft having an outer surface extending between a first shaft end that extends into the first bore and a second shaft end along the first axis,
• the shaft defining a notch defined by the shaft that is disposed proximate the first shaft end and extends from the outer surface towards the first axis,
• wherein the notch includes a surface that is linear and at least one of inclined and declined relative to the second axis;
• the yoke body defining a third bore that is disposed opposite a counterbore and extends from the exterior surface towards the second bore along the second axis,
• the yoke body further defining a stop wall that is disposed between the second bore and the third bore,
• a fastener assembly that extends through the second bore, through the stop wall, into the third bore, and at least partially engages the notch, and
• wherein the third bore is threaded and the fastener assembly is at least partially threaded into the third bore.
