ABSTRACT:
A fastener for securing parts to 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 carried on the outside face of the nut for engaging the outside faces of the channel lips, and guide members extending from the clamp member to a position beyond the inside face of the nut. At least one of the guide members has a portion bent to provide a spring finger receivable in a recess in the inside face of the nut to hold the clamp member in assembly with the nut. The spring finger is also engageable with the nut for providing spring action tending to draw the clamp member in the direction back toward the outside face of the nut thereby to clamp the clamp member and nut against respective outside and inside faces of the channel lips.
