Abstract
An improved releasably securable fastening system for attaching to a complementary receiving surface is disclosed. The fastening system features an engaging means in the form of a hook-shaped tine. The engaging means is longitudinally spaced away from, or above, a substrate by an upstanding shank. The engaging means forms an included angle, relative to the perpendicular from the plane of the substrate, which is greater than 180.degree. so that the engaging means has a reentrant segment. The reentrant segment of the engaging means provides for more effective securing of the fastening system to a receiving surface. An engaging means having an included angle greater than 180.degree. provides improved resistance to forces which cause separation of the engaging means from the receiving surface.
