An archery bow cam string stop includes a titanium stop, a titanium fastener and an impact portion. The titanium stop includes an elongated body. A female thread is tapped in one end of the titanium stop and a counter bore is formed in an opposing end thereof. The counter bore reduces the weight of the titanium stop. Two parallel flats are formed on opposing sides of the elongated body, adjacent the female thread to receive an open-end wrench. A cross-sectional shape of the elongated body is preferably round. The impact portion is preferably a plurality of o-rings. The plurality of o-rings are slid over an outer perimeter of the elongated body. In use, a threaded end of the titanium fastener is inserted through a stop slot in the string cam. The threaded end is threaded into the female thread and tightened to retain the titanium in position.
