metric threads 1

[subnetgate]

I'm looking for M profile limiting dimensions for a M23 x 1 external thread. All charts go from m22 to m24.
Any reference would be great. It is not listed in ASME B1.13M-2005 Metric Screw Threads: M profile. Thanks

I suspect that an M23 thread is considered non-standard and besides, a thread that large with only a 1 mm pitch, it would be an ultra-fine thread, not something that you would expect to be used in a fastener.

Try ISO 965-1. Limits will need to be calculated.
