This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

ive seen these used sticking out of concrete, the bend acting as the anchor... then the wood is bolted to this.
J Bolts for concrete don't have a head on them. The bent part is embedded into the concrete and would never be turned. Forming a hex head would be a wasted extra production cost.
I could see but it seems like a washer would be a much easier way to do this rather than bending like that
Even with a washer, the head of a straight bolt won't hold very well in concrete when you go trying to tighten it, it'll most likely start spinning and possibly even damage the concrete.
That’s true. I was thinking pull through but you’re right about spinning while tightening.
