A composite scaffolding plank made from a plurality of wooden boards positioned in side to side parallel abutment. A plurality of spaced pins extend transversely through the wooden boards. A cam means on the pins pulls and holds the boards together. In one preferred embodiment where the plurality of wooden boards are from a single board that is ripcut, the strength of the wooden plank is increased by cutting the plank longitudinally, positioning the resulting sections in side to side parallel abutment with the wood grains alternating directions, and to subsequently embedding a plurality of spaced pins in the sections.
