Rattle & drop or electrolytic seizing?

Given he's about to start drilling with extreme prejudice, I'd say the latter.

One out of 5 solid, now turned into a pile of swarf:)

Stainless coming to replace them.

bit of a toss-up as to which is less suitable for our glorious climate; them or alloy spoke nipples..... ::-)

Oddly, I’ve never struggled with the wheels I’ve used alloy nipples on. There again, I’ve never needed to true them.

Sorted with steel bolts and top hats. 3 rings on my Spa again - 48, 38, 30 and 12-30 10sp on the back. Just put a pair of Jack Brown Green tyres on and like them a lot. Smooooth.

Here's to hoping that you never need to then, my LBS won't even try anymore they just rebuild using brass nipples.
Quicker easier & cheaper than faffing around trying to free the seized alloy ones.
2-3hrs to strip & rebuild V's all day to unseize and true up.

I've got three wheels with anodised alloy nipples, on an ICE Vortex FS trike, and the first thing I did was to rebuild them using copperslip.
Even though they were 'New' I had to replace around a dozen spokes & nipples where they had seized and had to be cut off.
Not had any problems with corrosion/seizing in 9yrs now (I true & tension annually).

Alloy chainring bolts should be fine. I have never used anything else. Just assemble with grease (I use Shimano white assembly grease) and do not overtighten. The ones I currently use are 20 years old.

As for spoke nipples always use brass. Ventured into alloy once, never again. The tiny weight advantage is just not worth it. To delicate to assemble properly and prone to seizing onto spokes.

Aren't alloy chainring bolts (at least the inner "nut") pretty much standard? They're not highly stressed anyway.

With stainless steel bolts £2 for 5 I’d stick with SS.

Steel seems to be standard in chainsets from the factory. I’ve only seen alloy in the aftermarket.
