M6 x 0.5, 0.75 & 1.00

M8 x 0.75, 1.00, 1.25 & 1.5

If going for the M8 a 1.00mm pitch would make calculations easier but you will likely have to cut the thread yourself. M6 will be available off the shelf as nuts, bolts, studding etc

Are those figures for Metric Fine or Metric Coarse?

Jason's are metric fine and the others are standard metric threads

Which ones do you get when you buy a metric bolt or screw thread from Acme Building Supplies? I usually just see Metric.

Roger

A more accurate way is to measure ten threads, and divide the answer by ten - using this method should give you a reasonably accurate result using a rule, for those that don't possess a vernier caliper.

The easiest way of all is to pick up a set of thread guages from your local tool supplier!

The distance between the "peaks" on the thread is known as the pitch, and is the distance that a nut will travel during one full revolution.

M18 is the one with the most sizes of taps & dies available, 6 different pitches in my catalogue. Then you can always use the Metric angles and cut your own threads if you have got the right machines
