Open the CIPO recordAbstract From the Canadian patent
A nut plug assembly for use with structural poles includes a nut bolt and , washer attached, to a nut secured to the pole. The plug assembly remains within the pole nut throughout the, galvanizing process and would be readily removed by the user just prior to having a need to use, the pole nut for attachment of an accessory structure. As the nut plug assembly would remain in, the nut after the galvanizing process rust appearance would be minimized as the threads of the, nut would not be exposed. It is only upon the user needing access to that particular nut that the, plug assembly would be removed and an accessory component would be immediately inserted, into the desired nut.
