Abstract of the Disclosure A structural rack comprising a column and a beam, each made from a standard channel with a web and two tapered flanges, and a bolted connection between the column and the beam. The tapered flanges of the beam are notched so as to form an internal corner, into which an external corner of the column is fittable. The bolted connection uses a conventional bolt and a special nut, which has a flange-engaging surface conforming to a curved surface where one of the tapered flanges of the column meets the web of the column. Upon relative movement of the column and the beam as the bolt and the nut are tightened, the flange-engaging surface cams the last-mentioned flange against adjacent edges of the notched flanges, thereby to assemble the beam and the column with the external corner fitted tightly into the internal corner.
