I'm trying to figure out what this is called. This was used in a basketball hoop to connect a piece of square bar to a flat metal frame. The bolt went through the metal frame, then into a hole in the metal square bar. When tightened, as you'd expect, it snugly secured the frame to the square bar.
It's frustrating because I'm not sure what to call this thing. It has a "leg" that's a little different than J-bolts or the 90-degree anchor bolts that I've seen advertised.
Any ideas on what I should refer to it as? Also, is this a "standard" bolt or is this some weird one-off thing that no one else uses?
