Strange bcd cranks and a strangely threaded chainring, seems like a recipe for trouble.
The female part of the usual chainring bolt setup also locates the chainring by extending through both the crank and the ring. Forgoing the female part in your set up and using the bolts you linked to would leave the ring ‘located’ by the threaded section of a male bolt which sends sub-optimal (cue @gbj_tester to tell us if using a bolt in this manner is fine or likely to end in fiery death?)
I wonder if that chainring is meant to be used with a shoulder bolt though a bit of Googling has failed to bring anything up.

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

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
