I lost rack accessories once again

Some bad luck is chasing me and I can run from it . Some time ago I decided to design and to build a small server room or rather a computer laboratory I my basement. I ordered all necessary things and I started to work. But it was nothing new to me that during mounting of server racks there were missing some rack accessories. It is normal situation because producers are always trying to get some money on additional rack accessories. They not giving appropriate hardware or not enough spare parts to install the racks and cabinets. As I said I was prepared for this situation and I ordered some additional rack accessories. And then problems started. The package with hardware was not delivered to me. As it turned out the delivering company lost it. I got my money back but I was still missing additional parts that I needed to complete my server room. Then I decided to buy rack accessories in a more traditionally way so I went to a local computer shop. They told me there that I had to wait two weeks for the parts. After two weeks I finally got my rack accessories but when I was going back home by a bus I left the bag with the accessories in the bus. I went back to the shop and I bought another package and guess what? The rack accessories were so bad that I could not mount even one cabinet. Now I think that I will have to go to a regular shop and but some screws. Anything would be better then that.
