A screen table and tong assembly whereby a sand screen table structure adaptable to a rotary table is used to capture and suspend sand screen subsections within the well bore is further adapted to include a pair of articulated opposing manual tong assemblies. The tong assemblies are pivotal and transversely positionable relative to the screen table. Provisions are made for adapting a slip set in cooperation with said screen table and tong assembly for capturing and supporting wash pipe within the sand screen subsections. Additional adaptations include a custom spinner tong assembly for rotating the sand screen tubular subsections and wash pipe sections.
