Ocracoke Island, of course, boasts one of those historic lighthouses.
But Ocracoke is not a screw-pile lighthouse. Screw-pile lighthouses were designed to be placed in sounds, bays and rivers. Typically they were one-and-a-half story buildings mounted on threaded wooden (later, steel) pilings that were screwed into the sandy or muddy bottom.
According to Wikipedia, "Perhaps as many as 100 spider-like, cottage-type (1½-storey wooden dwelling) screwpile lighthouses were built...." NCpedia claims that "At least six screw-pile lighthouses hovered over North Carolina's sound waters in the second half of the nineteenth century."
One of those screw-pile lighthouses was located in Pamlico Sound. Built in 1904, the Bluff Shoal Lighthouse was located about 7 1/2 miles from Ocracoke. It is no longer extant.

I believe the Roanoke River lighthouse (mentioned above) may be the only North Carolina screw-pile lighthouse still existing and restored to its original appearance, although it has been moved to Edenton.
