A vehicle article carrier system for use on an outer body surface of a vehicle. The system may have a pair of support rails secured to the outer body surface. At least one cross bar having a pair of end supports extends between the support rails. Each end support has a housing and a rotatable locking component secured to the housing for rotatable movement. One of the housing and the rotatable locking component has a biased implement projecting therefrom, and the other has a plurality of structural elements arranged in a circumferential pattern. The biased implement engages with at least one of the structural elements to provide an additional holding force to the rotatable locking component when the rotatable locking component has been tightened.
