ABSTRACT:
A sheet metal wall stud having a shape and dimensions corresponding substantially to wood studs and a cross-sectional configuration providing for rigidity and dimensional stability. A wall system employing such a stud wherein top and bottom plates of conventional lumber are employed and a strip of particle board is interposed between the ends of the metal stud and the surfaces of the plates. The ends of the stud are formed to penetrate the surface of the particle board to afford positional stability for the stud and the stud is provided with nailing extensions to attach the stud at its ends to the top and bottom plates. Wood blocks installed at the ends of the stud transmit the bearing force between the plates and the stud, and the stud is provided with improved knock-outs for the passage of utility lines therethrough. Improved nails for securing wall panels, such as gypsum board, to the studs are provided. The nails have eccentric points so that as the nail is driven through the stud, it is deformed along a curvilinear path to inhibit its withdrawal.
