i have requested thumb screws (im assuming thats the screw type You mean) from atleast 3 different Case Manufacturers, as well as replacement side panels. Cougar sent me a giant shipment of 6 (Yes SIX) different types of Side panels (windowed & non windowed) , and a Massive bag of 50 Thumb screws
, Phanteks has sent me the best quality thumb screws, but they only sent 10-15 (i cant recall) as well as replacement front control boards (power /reset/ etc). Thermaltake has done the same, all i had to do was ask, I recommend You try the same ,especially with a company like Fractal, i would assume their response would be more than acceptable for You..... I dont think I even had to provide proof of purchase, just a pic, and explanation, saying that My case screws kept stripping, and Viola! give it a try, (if You havent). Shipping was always covered so all it ever cost me was the time to type the Email.
FRACTAL SUPORT
