A fastener arrangement includes a fastener, a slider, and an injection-molded end stop. The fastener includes first and second tracks. The first track includes a first profile, and the second track includes a second profile for interlocking with the first profile. The fastener extends between first and second ends. The slider is slidably mounted to the fastener for movement between the first and second ends. The injection-molded end stop is located at least one of the first and second ends. The end stop terminates the movement of the slider at the one of the first and second ends. The end stop includes interior plastic material disposed in an interior of the fastener between the first and second profiles. The one of the first and second ends includes a cut edge at an angle relative to an axis of the fastener extending between the first and second ends. The end stop may include exterior plastic material along an exterior of the fastener outside the first and second profiles and covering the cut edge. A method of forming the end stop is also disclosed.
