A bone fixation assembly is provided and may include a fixation member defining at least one aperture. At least two locking features may be circumferentially spaced around an inner perimeter of the at least one aperture and may include a first end and a second end. The at least two locking features may each include a longitudinal axis extending substantially perpendicular to an axis extending through the at least one aperture. A fastener may include at least two discrete locking members respectively received in the at least two locking features at the first end. The at least two discrete locking members may be circumferentially spaced around an outer perimeter of the fastener, may extend from an outer surface of a head of the fastener, and may be received within the first end in an unlocked state and rotated from the first end to the second end in a locked state.
