ABSTRACT:
A thread cover is attached to the terminal end of a threaded shaft in a releasable manner. The thread cover includes a main body having a magnet at one end thereof and a plurality of flexible arms affixed to the opposed end thereof. The main body is magnetically attached to the threaded shaft end, and the flexible arms are arranged to be adjacent to and cover the main body as well as the threads of the shaft end. When the threaded end of the shaft is extended through a seal means, the arms prevent the threads of the shaft from engaging and damaging the interior of the seal means. After the threaded end of the shaft has been telescopingly extended through the seal means, the thread cover is easily removed from the shaft end.
