ABSTRACT:
A fastener for securing parts to metal framing such as channel framing having side flanges with inwardly, 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 that of the slot. The fastener also includes a clamp member secured to the nut for clamping the nut on the channel. The clamp member has a crosshead which is spaced outwardly from the outside face of the nut and which is longer than the width of the slot. The clamp member also includes a spring latch which is sprung into engagement with the inside face of the channel framing when the nut is in a position wherein its outside face engages the inside face of the framing on opposite sides of the slot, thereby to bring the ends of the crosshead into clamping engagement with the outside face of the framing on opposite sides of the slot and the nut into clamping engagement with the inside face of the framing on opposite sides of the slot.
