A structural steel beam connects to a supporting column centerline using a Grade 50 single plate shear tab designated as Plate 'A'. Two vertical lines of 1 1/8-inch diameter A490-SC slip-critical bolts fasten the web of the supported beam to the shear tab, with the exact number of bolts determined by the structural schedule. Edge distances and bolt spacings follow specified dimensions, including 2-inch and 3-inch typical increments from centerlines and plate edges. The detail indicates a single plated drag connection on the structural plans.
