It's just regular chainring bolts.
Quite a few narrow wide chainrings are threaded too, makes more sense than requiring a female nut.

makes more sense than requiring a female nut.
Does it though? I can see the functional advantage if the bcd is large enough and tooth count small enough that the chainring nut would be in the way. Otherwise it seems like it takes a thread that’s normally, or at least very often, in steel and replaceable and makes it both non replaceable and from a weaker material.

Hi there,
Recently bought a Renthal chainring (apparently exotic 120 BCD) to fit a Raceface Turbine 10s crank..
Trying to mount the chainring I realized need uncommon chain bolt as the chainring is fileted (so only need the “male”)
The needed chain bolt diameter is larger than a standard M8 chain bolt..
Looks like is need 10mm diameter bolt with 0,75 filet..

This look like it would fit, by they’re expensive and I’m not sure of the standard
Can anyone help me out with this ? Cheers
