[QUOTE="ntsqd, post: 2224468, member: 93138"] Go ahead and try to duplicate the OP's screw from the hardware store. I am not saying that it can't be duplicated, it can. I am saying that it will be nearly impossible to do so from a hardware store. ANY hardware store. Factor in the country of origin and they're likely metric. Which makes it even more unlikely to source from a hardware store in the US. I once worked with an Engine Designer who insisted on using extra fine to ultra fine metric thread pitches (M3 X 0.3 anyone?). We had to have taps and dies made in order to meet his specified threads. They technically were standardized metric pitches, but nearly no one ever used them and the tools to make them DNE anywhere in the known world. Looking at the OP's pics it would not surprise me at all if this screw was in that range of thread pitches. [/QUOTE]
