Abstract
A touch fastener product for releasable engagement with itself or another fastener product at various engagement angles, has a sheet-form base and an array of fastener elements with stems integrally molded with and extending from a broad side of the base to a distal head overhanging the base. The fastener elements are arranged in various ordered patterns of straight rows, with the heads of the fastener elements covering the base at a desired head density. The fastener elements define a sufficient number and pattern of pockets between associated groups of adjacent stems to provide a desired bulk locking ratio when engaged with an identical pattern at a zero degree engagement angle.
