An improved sink drain device that includes a main sink drain member, upper and lower gaskets, a threaded ring and a plurality of pressure bolts. The sink drain is funnel shaped and has an outwardly extending flange at its top-most surface and has external threads on its outer surface. The threaded ring has internal threads that engage the external threads of the sink drain member. The threaded ring also has threaded apertures. The upper gasket is located between the sink drain flange and the top surface of the floor of a sink. The lower gasket is located between the lower surface of the sink and the rigid pressure ring. The pressure bolts thread into the apertures of the threaded ring causing the flange of the main sink drain member to be forced downward to form a water-tight seal with the floor of the sink base.
