For your info on the Radiator cap set screw.

[Micksan]

Yesterday I got in a new horn. To beat the heat and have a few hours to kill before a doctor app. I did not know that the radiator cap has a set screw. They bend very easily. Ace Hardware has them, along with a fallen wrench. I picked up an extra screw just in case. Now that I have a spare I will probably never need it.

The ole hidden that bends easy radiator cap screw i bet its got many. My tuner called oneday said cap wont come off, i had already removed the set screw but you have to mash down then turn to get cap off, set screw got thrown away along time ago.

Yep. Same with the older gens.
I have 2 back up screws left out of the 4 I purchased. The 1st one was stripped!
I tapped in for a larger thread to make it work this why I need extras.
A magnetic bit works great!

Tell me about it.

Well the older ones are not that big of a deal. Just tiny and get lost easy or stripped out. That looks like a huge pita

The second thing I removed twenty years ago right after the safety warning labels.

I wonder if there's a sufficiently narrow and long hairpin cotter-like solution that would work better.

 

[Mongler07]

Probably. But a harder grade bolt with only threads where it needs it would be better.
