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.
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.
ive seen these used sticking out of concrete, the bend acting as the anchor… then the wood is bolted to this.
I could see but it seems like a washer would be a much easier way to do this rather than bending like that

That’s true. I was thinking pull through but you’re right about spinning while tightening.
