Y0MZ98110 (FC-R9100) / Y0MZ98110 (FC-R8200) - 46T-NH is the same for Dura-Ace and Ultegra
Y0MZ98120 (FC-R9100) / Y0NG98080 (FC-R8200) - 4pcs chainring fixing bolt (M8 x 10.1) and nut
The reason there's different bolt/nut packs for 9100 and 8200 is because they incorporate the bolt cover which is intended to give the 46t a more integrated look with the respective crankarms spider.
