| 摘要 |
This invention relates to a bolt having a tapered tip comprising of corresponding opposite flat and partially threaded portions that engage an oval nut having elongated internal adjacent sides, the ends of which are void of threads to enable bolt/nut alignment when initially inserted and tightened. Additionally, the tapered threaded bolt has an arcuate shaped or rounded first and/or second thread for providing self-alignment and preventing gouging or digging of internal threads when being inserted or screwed into any conventional nut or oval shaped nut. Moreover, inadvertent contact between the bolt and nut while in the process of initial insertion will not preclude uninhibited correct bolt insertion into the nut.
