There's a good reason these were unsorted. Divide the collection by all things likely, you'll be lucky to find a dozen same items. Then what?

If you really want to:

This set of thread checkers and diameters should identify most bolts. Then use the known bolts to find their mating nuts.

A more useful endeavor, I think, would be to let this assortment gather dust until you have a need for something, and buy a box of it. Then rummage for pieces matching the proven useful hardware on hand.

You pretty much need a known thread count and gauge as Kobuchi has said.

I have a very large collection of all types of fasteners and find it much more convenient to keep them in bins of matching and similar gauge but differing lengths.
As an example I would likely have 500-600, 1/4"-20 (1/4" NC) hex head bolts organized in three bins...... short-med-long.
Wood screws as well are sorted this way and then I just take the time to dig through and match lengths for a specific project.

Trying to sort all that, (they way you specified) will drive you (and yer other half, if there is one) crazy.

I've found if I just get them semi organized, I'm pretty happy.

First do machine screws vs bolts vs wood screws vs sheetmetal screws. Once you have it in those categories (or however many you like), you can sub-divide 'em down by size and length one type at a time, if you like.

Use coffee cans or other suitable container initially, then go to smaller and smaller as you break 'em down. The inexpensive throw-away (who does that anyway?) tupper-ware type containers from the discount stores (big-lots, general dollar) make it pretty easy to label and stack.
