Abstract
A fastener for securing parts to metal framing (e.g., channel framing) having side flanges with inwardly turned, hook-shaped lips defining a slot therebetween. The fastener comprises an elongate body or nut having inside and outside faces, opposite sides and opposite ends, a width less than that of the slot and a length greater than the width of the slot. The fastener also includes a clamp member secured to the body having portions generally adjacent opposite sides of the body engageable with the outside face of the framing when the body is aligned with, entered into and passed through the slot in the framing. These portions remain substantially stationary with respect to the body when the latter is turned to its crosswise position. The clamping member also has resilient clamping portions generally adjacent opposite ends of the body engageable with the outside face of the framing when the body is turned to its crosswise position. These clamping portions spring away from the outside face of the body when it is turned to its crosswise position for providing a spring action tending to draw the body into clamping engagement with the inside face of the framing.
