On a finished hatch or a deck box lid, a protruding screw head is an eyesore — and a snag point. The countersunk holes on this 316 SS flush hinge let the fasteners sit perfectly level with the hinge surface, giving you a clean, flat installation that looks intentional and won't catch lines or fingers.
