Also why would you need to replace it? It looks like it lost its dust cover, but its a cosmetic part anyway

There will be a replacement available from Sram that will replace both the bolt and the self extracting cap cover that you lost. Sram has deep splines so quite hard to wreck the crank but not impossible, but I do recommend getting the proper replacement.

Looks like a square taper BB, so it should be a standard crank arm bolt. It comes with an inbuild wide washer [example](https://www.amazon.com/Truvativ-Capless-Steel-Crank-Bolts/dp/B001CK2H8A)
Its a M8x20 with a 1.0mm thread pitch
