Abstract: A fastening assembly for attachment of objects (1) to substrates (2) formed from friable materials, such as plasterboard, includes one or more longitudinal pins (8) having threaded head portions (10), which thread into one or more corresponding threaded apertures (3) in the object, such as a bracket. Each pin (8) has a shank (11) which passes through the aperture (3) in the object (1), and through the substrate (2), such that an end of the shank (11) preferably protrudes through the substrate (2) before the threaded head portion (10) engages the threaded portion of the aperture (3) to lock the pin (8) to the object (1). The apertures (3) in the object (1) may be arranged with their axes at different angles so that the pins (8) pass into the substrate (2) at different angles.

Abstract: A fastening assembly for attachment of objects to substrates (16) formed from weak or soft construction materials, such as plasterboard or chipboard, includes a bracket (1) having one or more apertures (3) and one or more longitudinal pins (8) having threaded head portions (10), which thread into corresponding apertures (3) in the bracket. The apertures (3) in the bracket (1) are either obround or star-shaped and may be punched out from the bracket (1). The pins (8) are arranged to pass into the substrate (2) at different angles through the apertures and their threaded heads lock with the walls of the apertures.
