Abstract: This invention relates to an adjustable fastening surface device with an integral releasable thread form. This device allows the adjustable anchoring of materials to hardened concrete or similar cold castable material with relatively low tensile and shear strength properties when contrasted with the compressive strength properties. The fastening device is cast or inserted into concrete or similar material prior to setting or curing, or can be inserted into cold castable material contained within a suitable void in any hard or impenetrable substrate.

Abstract: A component (20, 22) and method for a casting process, typically for cold-process casting of concrete wall, floor, ceiling or other panels or element in situ in building construction, leaving embedded in the cast panel a fastening surface (24) which can be adjustable to allow correction of non-uniform cast surfaces. The component may be integrated to conventional form-tie systems which use ties to space removable/reusable forms, holding forms a set distance apart, and can also hold a barrier material (typically expanded foam insulation) against the inner surface of a form(s) while casting is underway; when the forms are removed, leaving a component embedded providing an adjustable surface suitable for attaching material such finishing sheet material. The component can allow adjustment of its mounting surface with respect to the cast surface and to other like components in the cast panel to provide for (substantially) uniform surface for mounting finishing materials and/or fixtures.
