That there is a doodad, not to be confused with a thingamajig.

Could’ve been a makeshift hook. Or a lock pin/bolt (literally) for one of those simple gate latches.

I read they’re doing a recall on the left bend one. The right bends are okay tho.

These bolts are like this from the factory - I have 4 on my honey extractor, they are used for other situations where you need to bolt one thing perpendicular to each other.

Could be useful as an allen 🤔
