| Outline of Final Research Achievements |
The following guidelines were obtained concerning the optimal design for nuts with flange mated with bolts: (1) The flanged part increases the rigidity against the radial deformation of nut, and leads to boost the loadability of mating threads;(2) newly proposed light weight nuts with flange decrease the local stress on the thread root of bolts mated. The stress level is affected by the incomplete thread and the geometry of countersink of nut bearing surface side; (3) no harmful effects were observed during the manufacturing process and the quality assurance tests for the newly designed nut.
