Harry is referring to "thread gauges," AKA "thread pitch gauges." See:

http://en.wikipedia.org/wiki/Thread_pitch http://www.google.com/products?q=thread+gauge

I'm lucky to live close to a world-class hardware store (Hardwick's, in Seattle), and a few years back I picked up three sets of gauges that together cover just about every metric and standard thread pitch imaginable. (Well -- maybe not the thread pitch on those bolts they use to fasten cable stays on suspension bridges, but for those I suspect a yardstick would suffice.) I originally got them for a massive old-house repair project (plumbing, lighting, wiring, ventilation, etc.), but I can see that they are going to be just as handy for working on bikes.
