I won't replace the ones holding the stays onto the frame - they're heavily loaded in sheer when the bike's folded. However, the ones holding the stays onto the mudguard are only lightly loaded, since the weight of the bike itself is taken by the stay, and the bolts merely stop the stay (which curves round inside the mudguard) from slipping out of place. And if they break, I'll switch them for steel. And curse a bit.
