Abstract
A one-piece thermoplastic fastener assembly is disclosed having a friction-weld fastening surface with a centrally located heat-activated adhesive pellet. A plurality of deflector segments are integrally formed with the friction weld surface at the plurality of radial distances from the axis of rotation. The shape of the base member and the thickness of the plurality of deflector segments are selected to cause any imaginary straight line emanating from the axis of rotation and passing through the marginal edge of each intercepted deflector segment to extend below the radial plane which passes across the outer marginal edge of the innermost deflector segment to thereby causes even distribution of the heat-activated adhesive across the friction weld surface in response to a driving rotation of the base member.
