Abstract: In one embodiment, a bonding nipple for use in building electrical systems has a tubular-shaped body attached to a tubular-shaped head. The body and head share a common axis, and the outer diameter of the head is larger than the outer diameter of the body. The exterior of the body is threaded to form a male connector. The exterior of the head has a hole situated thereon to receive a grounding screw. In one exemplary installation, the body of the bonding nipple is fed through a punch-out of a service panel into one end of a female-threaded coupler, and the coupler is situated over a male-threaded conduit. The coupler is tightened over the conduit and the nipple until the wall of the panel is sandwiched between the coupler and the bonding nipple head. A wire is then connected between the grounding screw and a grounding bus bar in the panel.
