Flange Joints - Threads engagement

[Corgas]

In ASME B31.1 parag 108.5.1 : "Bolts and bolt studs shall extend completely through the nuts".

Is there a similar wording in ASME B31.3?

Thanks,

Corgas

Yes, see ASME B31.3(-2010 edt.) para 335;

335.2.3 Bolt Length. Bolts should extend completely
through their nuts. Any which fail to do so are
considered acceptably engaged if the lack of complete
engagement is not more than one thread.
