may be there is somebody else out there who wanted to buy a screw to change or build up the equipment.
I found a reseller for this: for my dutch colleagues it is Fabory Nederland, but they work in 15 countries.
Going to the shop itself, you can buy a single screw, no need to buy a pack of 50. A lot of things are in stock, some have to be send to the shop in a few days. You can also get the necessary instruments to drill and cut BSW. To see prices you have to register as customer, cause you can not see them in the online catalogue. Or just call your local dealer.
I think this expands our possibilities beyond the gitzo, manfrotto etc prefabricated few screws on the market.
