Abstract
Various improved methods are provided for fastening two of more steel framing members together with a fastener. In one aspect, the fastening technique employs a fastener having a tip section such that a portion of the tip section extending beyond the underside of the framing members may be outwardly flared, thereby inhibiting removal of the fastener from the framing members In another aspect, the fastening technique employs a fastener having a steel tip nose for piercing the framing members and a plastic stem section, such that a portion of the stem section extending beyond the underside of the framing members expands, thereby inhibiting removal of the fastener from the framing members. In yet another aspect, the fastening technique employs a fastener having a coil section with an elastic characteristic.
