Joe's right, it should be the right one. The parts charts I have are for the white FWs, and lists part 248 for the screw. I suspect them to be the same as the other FW machines.
You got lucky though. If it was a 301 (50087) a 15-91/125 (246), 201-2 (246), 285 (120) , it wouldn't have been the regular screw. And the 301 screw is pretty much unobtainium. I'm not positive on the others, but they're not in my parts list from my supplier.
