A flange apparatus operable to connect the discharge of a plumbing fixture to the waste drain pipe of a drainage system. In an embodiment, the flange apparatus includes a flange and a flexible sleeve disposed through a central opening of the flange, in which a first portion of the flexible sleeve is seated on the flange. The flange further includes arm portions, each having an aperture defined therethrough. The surfaces of the apertures are substantially smooth, and the apertures are operable to receive fasteners. In an embodiment, the arm portions may be made of threadable materials, and the fasteners may have thread-forming fasteners such that threads are formed in the arm portions when the thread-forming fastener is received in the aperture of the arm portions.
