Image Number 3 for United States Patent #5309490.

A device 20 for cleaning threaded studs 14 securing the dome-shaped head of a nuclear reactor pressure vessel to the vessel body 10 comprises a cylindrical brush holder 24 rotatably carried in a housing 22. An annular steel wire brush 28, disposed on the inner surface of the brush holder 24, is adapted to fit over and engage the threaded portion 14a of a stud 14.
