Hello. I have a folding knife that I really like. Unfortunately one of two screws holding the clip on, worked it's way out and got lost. I'd like to get replacement screws and put the clip back on. I recently ordered the 2-56 button head 1/8" screws and the thread part of the screw is not thick (wide) enough. How do I determine the width of the screws for sale, and how do I get an idea of what replacement screws I should order? Thanks in advance for any help. (p.s. I cannot find the knife on the web based on the manufacturer to try to get replacement screws that way.
