     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. 
     According to an exemplary embodiment, a clamp includes a clamp body and a clamp leg. According to an exemplary embodiment, the clamp body includes an annular cavity to receive the clamp leg. According to an exemplary embodiment, the annular cavity and the clamp leg each includes internal female threads. According to an exemplary embodiment, a fastener (e.g., a bolt) fastens the clamp body to the clamp leg such that no threading is externally exposed. 
     According to an exemplary embodiment, a bracket includes slots to receive the clamp leg. According to an exemplary embodiment, when attaching the clamp to the bracket, the clamp leg rotates, which is caused by tightening the fastener, and allows a foot portion of the clamp leg to anchor against a wall of the bracket. As the fastener is continued to be tightened, the clamp body and the clamp leg may be urged together, and the clamp may be further affixed to the bracket. 
       FIG. 1A  is a diagram illustrating an exploded, side view of an exemplary embodiment of a clamp. Clamp  100  includes a fastener  105 , a clamp body  110 , and a clamp leg  130 .
