All Sizes & Colors: Buy Plastic Milk Crates at Amazingly Low Prices! Save on Plastic Milk Crates!

Would it be more beneficial to try and sell 270 milk crates worth of bolts, nuts and screws, or scrap it all?

Not sure where to even start on something like this, but my boss has 10 pallets with 270 milk crates full of screws, nuts, bolts, etc. Overall it’s a quite a lot of lbs., but didn’t know if there is a market outside of scrap. Any insight would be appreciated.
