7/16-20NF HSS bottoming tap

The Cleveland C54663 is a 7/16-20NF bottoming hand tap manufactured from high-speed steel with a clear finish. It features four flutes and a G H3 pitch-diameter limit for accurate thread cutting. Designed for through-hole and blind-hole tapping in general-purpose applications, it suits maintenance, repair and light production work where reliable thread quality is required.

Machinists needing a bottoming tap for fine threads

This tap suits users cutting 7/16-20NF threads to a G H3 tolerance in steel, aluminium or plastic. It is not intended for buyers who need a taper or plug chamfer for starting threads, nor for those requiring a different thread size, pitch or pitch-diameter limit. Shops needing coated tooling for high-volume production or exotic alloys should evaluate alternative tooling.
