ABSTRACT:
An improved mechanical donut and donut assembly in which donuts made of plastic materials are formed in segments that facilitate installation, removal and/or replacement for manufacture and maintenance. The donuts of the preferred embodiments are made of urethanes, especially polyurethane, while fastening members such as threaded bolts are made of nylon. The relative characteristics of the urethanes and nylon are such as to facilitate a self-tapping feature for the nylon bolt.
