over_clox,

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.

ive seen these used sticking out of concrete, the bend acting as the anchor... then the wood is bolted to this.

Tandybaum,

I could see but it seems like a washer would be a much easier way to do this rather than bending like that

over_clox,

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.

Tandybaum,

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

geekworking,

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.
