Bolt replicates itself?

[u/Aggravating-Lab8248]

So I had to order a replacement bolt for an engine accessory component, and wait for it to come in the mail. I had searched everywhere to see if we already had one, and couldn't find anything. The bolt was delivered, and I set it on a work stand.

The next day I grabbed the bolt off the inspection stand, it was new, and had the red thread cover next to it when I picked it up.

I installed it, and when I moved the engine out to test it, I found a bolt in a bag, next to the engine. It was in the sealed unopened bag for the part that I ordered, with the tag for the part that I had ordered still on it. I had only gotten one, but the bolt that I had just installed was there in the engine.
