Abstract:
1. A precision aligning fastener comprising: a first body having a first shank with a first mounting flange and a shaft; a second body having a second shank with a second mounting flange and a bore; a stop means for aligning said first body with said second body and for preventing overtwisting, said stop means including a stop pin projecting from an end of said shaft adjacent said first mounting flange and a stop at each end of said stop track having a stop, said stop track being recessed in said second mounting flange and constructed to receive and restrict travel of said stop pin; wherein said shaft has a threaded end spaced from said first mounting flange with a first male interrupted-thread pattern and said bore has a threaded bore end spaced from said second mounting flange with a second female interrupted-thread pattern; wherein when said first body is aligned with said second body such that said first interrupted-thread pattern is disengaged from said second interrupted-thread pattern, said shaft is insertable into said bore until said first mounting flange and said second mounting flange abut each other, wherein said first body is aligned with said second body such that said stop pin is slidably received in said stop track when said first mounting flange and said second mounting flange abut each other; and wherein threads on said threaded end engage with threads in said threaded bore end when said first body and said second body are counter-rotated relative one another for a partial rotation that is limited by said stop pin abutting against said stop.
