Yes. Button head machine bolts are extremely strong

Which is why things like jet engine cores are bolted together...

Rivets are CHEAP and LIGHT which is why they are used in AK's (cheap) and aircraft structures (both considerations)

Bolts are EXPENSIVE and HEAVIER which is why they are not used in aircraft structures, but this is why they are used in critical areas needing additional strength where weight is not an issue, and re-entry (IE disassembly) is possibly contemplated.

Bolts are just fine when you do not care about the cost, have back-space for the required hardware (washer and nut), and do not care about the cumulative weight of the additional hardware.
