These are all hex screws and the hexes are provided. Locking rings and washers are in the share a bin. Nuts and bolts have their own bins. I did not pay enough sttention to sizing. These are short with a few exceptions and half of the them are very small. The case is damaged with one lock broken off but the other holds it closed well enough. With the bubble wrap inside the lid, the pieces stay in their proper compartments even when the case is on its side.
