Good selection of M3, M4 and M5 pan head screws and nuts. The only problem was that the nuts and bolts got mixed up during shipping. The suitcase has to be bent in such a way that I have to go through all the compartments and put them back in the right places. Note: There are no washers, so if you need them you will need to purchase them separately. Also, none of the nuts are secured (nylon or gas-air). So if you need locking nuts, this set is not for you.
