An improvement to a multi-angle fastener for use in connecting a bone portion with a connecting member. The multi-angle fastener includes a rotating member having a central longitudinal axis and an outer surface; a fixed member having a central longitudinal axis and an outer surface having threading configured to be surgically implantable into a patient's bone tissue; and a joint for connecting the rotating and fixed members together. The joint including corresponding mating surfaces configured to articulate with each other sufficiently to allow the rotating and fixed members to angle relative to one another. The improved mating surfaces comprising a tapered flange and a corresponding tapered groove respectively configured to allow for increased fatigue resistance of the fastener when the rotating and fixed members are secured together.
