🔎 UNIDENTIFIED How old is it? I found a cast iron eye bolt as long as my fore arm with square nut. About 2 inches down.

I’d say that’s steel, not cast iron and modern based on condition. Linemen use some large bolts (directionally that size)on power poles, but not certain if they use eye bolts.

Agreed with N. The uniformity of the shaft and the threads show that is machine made, not handmade by a blacksmith.

It has a hex nut, Most all older bolts had square nuts.
