I had never seen the third brake light on a 40 mounted in the spare tire hub ever before. It’s such a great and useful add-on that I would be surprised if I was the first to ever think of it. But I love the added safety, and if I was the first to ever think it up, I suppose it should be referred to as the “Aloha Jen spare tire 3rd brake light” from now till the end of time…or at least till some else comes along and claims the idea before I had it in November of last year!
You should start manufacturing the Aloha Jen third brake light. I bet there would be a market for it.I had never seen the third brake light on a 40 mounted in the spare tire hub ever before.

Not to be a boring stickler but the WW2 era non-Copper cents were steel. It's the present day pennies that are mostly Zinc.
Very true as long as the item being protected is immersed in a conductive fluid.
She's very pretty!
Ooops!
I'd definitely chose a bolt rather than a screw - the problem is finding a bolt with a sufficiently short shank for the job.A simple screw-jack can be purchased, or fabricated from some correct length hardware (basically a bolt in compression, not tension). It presses the rivet in place between channel so that you can round-over the rivet with heat and a swage-block. A swage-block is nothing more than a dimple in a piece of steel, probably a drill-bit point is all that is necessary, and a handle. An acetylene torch, or carbon-arc-gouging electrode (for AGM/gel batteries or battery, or SMAW set-up) will provide the heat. It would be cake to mock-up a rivet-set-up to practice on some channel or box material. (I'm not speaking here from any frame-repair experience)
Screws are only as fat as the inside groove in the thread, so they won't exactly replace rivets regarding diameter, unless you drill-out the frame. Button-head screws will appear more correct, but, they are ideal for bicycles, Warn hub mechanisms, and office furniture. The material has to be really hard, so that the hex key or socket adapter doesn't strip them, but it is still a far cry from an external hex-head screw/bolt. I'd say that they are the wrong Class. Class 7 screws were used to hold the hub flange to the hub, subject to cyclical loading within the drivetrain, and corrosion (you'll see all kinds of lower Class screws used all over these rigs. This article describes many issues with simply using a stronger Class/Grade fastener to join soft material like components of a frame. I remember when a former Navy machinist told me that stronger fasteners are not necessarily better - it still has me buggin'-out.

Not all fasteners are created equally--some are stronger than others. This article looks at the different strength grades for both inch and metric sizes.www.fastenermart.com
The difference between a screw and a bolt is a nut and some washers. So, I was only referring to the critical part of the bolt, not the nut. I realize that we call them, 'head bolts.'
I'm a machinist, so my language doesn't necessarily fit in. If you look up anything in Machinery's Handbook, it will refer to 'screw threads.' At the hardware store, you select screws from one bin, and nuts from another. We are working with nouns. Anything with an external thread is a screw, like you said. A screw is a simple machine with a head and a helical thread. Engine heads are not secured by nuts, so I confusingly call them 'screws.' Button-head, socket head cap screw, slotted, carriage bolts, or hex, your choice. When you fasten it with a nut, then it is a bolt. However, regarding fastener failure, the article I posted was illustrating the failure of the screw, at the minor diameter, not broken nuts. Fastener fault consideration involves both ASTM testing, as well as ANSI standards.

I've really put the cat among the pigeons here, oops - it's just semantics though.
Did you see the Fastenall article? https://www.fastenal.com/fast/services-and-solutions/engineering/fatigue# Figure 12, - length X vs. length X+Y, more thread length = less concentrated stress. The minor diameter of the thread is the concentrated weakness, so it is better to distribute that over a greater length of the fastener.
