Well done @Leggy

Hi guys
Again thanks for all your help
Is there a chart you use to look up thread dimensions, pitch, tpi , crest etc
I was trying a m22 x 2.5 and got a bit confused on the chart I was following, so I asked ChatGPT
After 4 hours of me telling it, it was wrong, it finally agreed
I was drawing it in SU then asking it questions on the iPad
When I get home I’ll upload my figures and see what you think, the thread looks good on the screen, but that doesn’t mean it will fit
Thanks Dean -

I would use the following site:
External Metric ISO Thread Table Chart Sizes M20 - M55
Metric external thread size table chart for sizes M20 to M55 Bolts and screws per. ANSI/ASME B1.13M-1995.
(www.engineersedge.com)
I wouldn't bother with the radiused corners because they'd be too small.

Ill check it out

What about tpi?

What do you mean? The thread pitch is given along with the other dimensions for the threads. TPI standas for Threads Per Inch and is not used for metric threads. M22x2.5 indicates the nominal diamter is 22mm and the pitch is 2.5mm. The helix rises 2.5mm for each rotation.
