Touch fastener products (10) are made by distributing a multiplicity of discrete fastening bits (14, 14a, 14b) over a support surface (12) and fixing the distributed bits (14, 14a, 14b) to the support surface (12), such as by an adhesive (32). Each bit (14, 14a, 14b) has opposite side surfaces (24, 24b, 26, 26b) forming boundaries of surfaces defining projections (16) extending in different directions from the fastening bits (14, 14a, 14b), at least one of the opposite side surfaces (24, 24b, 26, 26b) being non-planar, and each projection (16) has an overhanging head (18). As fixed, each bit (14, 14a, 14b) is oriented with at least one of its projection heads (18) raised from the support surface (12) to releasably engage fibers (30). Bits (14, 14a, 14b) are made by pelletizing shaped rails (36). Applications include securing floor coverings (150).
