I apologize, I mistakenly wrote KCNC when I meant Token chainring bolts earlier.
Token chainring bolts on my SRAM Red/Qring are my current setup, in black.
But they have all sorts of colors. $12 shipped from Taiwan off eBay.
The front part uses a 6mm hex, the back uses a 5mm.
Also, I use blue loctite on the threads, no problems, just hand tighten. There are 5 of them, you will know if they get loose or one falls out eventually, but I never had a problem. Easy10 minute swap job being careful to ensure the hex wrenches are flush and you don't gouge the outside part slipping the hex wrench on them, ask me how I know!
Sram puts some white loctite or something on the threads, darn near nightmare getting the stock chain rings off initially to swap bolts. Could only imagine they are running them 15nm or something high. But I don't see why 8-10nm isn't plenty as a guess. Again, blue loctite, hand tighten them pretty good, don't go crazy, they will hold fine and look sweet!
