I bought some nice little stainless wing nut bolts on Amazon and replaced the two M6 seat bolts.
I've checked them a few times since putting them on and they've remained tight. I can now store my insurance/reg slip under the seat and if pulled over, the cop will just have to wait a few minutes for me to carefully remove my seat.
