This invention relates generally to an adhesive fastening device which includes a substantially flat base carrying on its undersurface a layer of heat activable adhesive. The fastening device may also include a section extending from the base designed as a secondary fastening feature, such as a stud, tab, clip or the like. Protuberances of limited surface area and height are formed adjacent the perimeter of the base in a pair of laterally spaced lines adapted to be associated with the end surfaces of a U-shaped core to slightly space the core from the base. |
