Are These Indicative of 19th Century Steamer

[callicles]

So I got permission to magnet hunt an old bend in a river where a steamship had supposedly sunk in the 19th century. I wasn't sure about the story. I did, however, recover items that certainly appear, to my untrained eyes, as coming from a boat.

I am hoping folks here could view the items and tell tell me whether they appear to be from a ship and, if so, do the items look consistent with a 19th Century one.

I suppose an easy - but likely ignorant - question is: did they have brass wing nuts back in the 19th Century? If that answer is no, then it may help me know it is not that old. (See picture below).

A few few other observations:

-on one of the bolts, there is a square nut on it. I've been told that square nuts might indicate it is old. Is that true?;

- a few items are fused together;

- one item looks like a modern key, but it obviously isn't. Any ideas what it could be? Maybe a toolbit unrelated to possible wreck site?;

- I have no idea what the other small brass piece is. It kind of looks like a rivet or something.

Any help is appreciated!

The one item looks like an old pencil compass, pretty sure they used them for plotting sea routes

thanks for your response. I think, though, the item you are referencing is a group of fused together nails and bolts. My pictures aren't the best, sorry. If you are referencing another item, let me know. Again, thanks for looking!

Pic on the left. If that wingnut is brass , I would say boat related. The square with point looks like a broken file. Square nuts are the old style but were used on farm equiptment until the 1940's and can still be found today.
