In a conveyor belt composed of hinged modular links, one or more of the links are composed of multiple parts at least one of which is in the form of an guide-engaging element having a protruding guide-engaging section, a pair of laterally spaced hinge knuckles on a leading or trailing edge of a base, and a single hinge knuckle on the opposite edge. The single hinge knuckle is positioned opposite the mid point between the two laterally spaced hinge knuckles. The sum of the cross-sectional areas of the two laterally spaced hinge knuckles is equal to the cross-sectional area of the single hinge knuckle. The widthwise cross-sectional area of the base of the guide-engaging element is equal to the widthwise cross-sectional area of any portion of the base of any other modular link in the belt having the same width as that of the base of the guide-engaging element.
