I have a smith and Wesson rescue knife and i lost one of the tiny screws that hold the pocket clip on. SW said i could send it back and they could warranty it but i figured it might be easier to just find a replacement screw. Problem is trying to find what size it is. I measured the thread diameter and it's .078" and I'm not having much luck finding something like that. Does anyone know where to find these small screws or how to figure out what size/thread pitch it is so i can do a better search?
