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.
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 is one of those right angle bolts for getting into tight places. Hang onto it because they cost about $15 each new. It is specially made to transfer the torque from the head around the 90 degree bend. Just line it up with the nut, slap a driver on there and go to town. I promise, it will be amazing and nothing bad will happen.
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.

What a remarkable bolt! Can it come and do my place when it's finished?

My first thought - aww, what a clever little bolt, and cute to boot!

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.

Ugh, happens to me all the time when I get overconfident trying to hammer in bolts.

At my old job we had some of these on the wall for hanging our hardhats.

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

I've had to help someone tighten a bolt like this before. It was used to attach the deck assembly to the underside of a riding lawnmower.

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

Very strange, but looks prebent
nogrub@lemmy.world · 3 pts · 3y
get yourself an acyzelen torch and then you can get your very own prebent 90° bolt for thoose tight spaces

Could be useful as an allen 🤔
Axefanatic@aussie.zone · 2 pts · 3y
This is the most likely reason. I made a few of these when a regular Allen/Hex key is needed in a larger size than what you have on hand.

Could be similar to DIN875 or DIN878, depending on who you ask https://www.scribd.com/document/81939727/Sonderschrauben-fur-den-Maschinenbau
