Pivot pins extend through the apertures to connect adjacent rows of links. Each link plate has a pair of teeth for engagement with a sprocket. Each tooth has an inside and outer flank. The outer flank has a flat surface which extends from a first end at the tip of the link plate tooth to a second end adjacent a corresponding aperture. Each tooth has a protruding surface near its corresponding aperture defined as a convex curved surface which protrudes in an outward direction relative from the flat surface on the outer flank of each link tooth adjacent a corresponding aperture and extending to a location on the link surface intersecting a horizontal centerline extending between the apertures.
