Calculated Thread Depths for Metric fine threads

[dp]

Oh lordy it raised a big ruckus the last time needles were brought up. I remember because it was me who said that, then. It turned out to be a good way to identify angry machinists

OK, the calculation again, with the correct thread pitch.

Based on M12 x 1.25 and Sharp Vee tool:

Depth of thread = 0.614 * pitch. Even for wrong pitches.

Thank you Thankyou Invaluable Help. Its appreciated .The mention of making a accurate gauge has merit, For a standard m12 x 1.25 pitch thread whats the best way to make a accurate gauge for the male to fit into my machined female Part? Thanx Mike

M12 x 1.25 is a standard Metric Fine thread so you should be able to find all the information you require in the normal thread tables.

I got an M12x1.25 6HX tap made specifically for blind holes in stainless steels. If you're a neighbor you can borrow it and be done, no gauge needed.
