Abstract: A fastener assembly includes a base including a front face and a rear face. The base includes one or more mounting openings extending through the front face and the rear face. The fastener assembly includes a mounting fastener received within the one or more mounting openings. The mounting fastener includes a length that is greater than the thickness of the base such that the mounting fastener extends through the mounting opening and engages a surface to attach the base to the surface. One or more fasteners are attached to the front face of the base. The one or more fasteners extend outwardly from the front face.

Abstract: A lightweight composite composition includes a plurality of lightweight particles including a volume of at least about 10% of a total volume of the lightweight composite composition. The plurality of lightweight particles includes an average bulk density within a range from about 0.001 g/cc to about 1.5 g/cc and an average particle size within a range from about 0.01 microns to about 90 mm. Methods of manufacturing a lightweight composite composition are provided.
