Abstract: A reusable single groove riveting system includes a single groove riveting bolt and a collar, and a method of use thereof as well as installation and removal methods thereof. A pull groove has a variable section feature along the axial direction so a collet and the single groove can automatically align during installation; the variable section can reduce the stress concentration effects along the single groove structure and avoid stuck problems. While raising the strength of the collar flange, the design feature of the axial installation force indicator is added. The single groove structure will not receive any extra load from the tool during disassembly or removal process so the rivet bolt can be reused after the disassembly. In the event the bolt pull groove is accidently damaged or the work space is limited, the collar can be effectively removed from the joint with this disassembly or removal method.
