Well first off you didn't say what your working on, but since your in the S2000 area it must ber the IGT S2000... I'm not very good when it comes to metric sizes and thread pitches. What I do is take some hardware to my local Ace hardware or just about any hardware store. In the aisle where they sell this stuff they usually have a thread gauge setup where you can try your parts for size. Then just go looking in the metric parts drawers for your pieces you want or need.. This is how I have had to do it in the past..
