Thread Specification
Thread Specification
(OP)
Hi,
Thread specified on a bolt drawing is "M2.5 x .45 4h".
Is the thread British standard ISO metric or ANSI/ASME metric thread?
Which standard do I need to refer to get minor, pitch dia of thread?
How do we know about the standard used?
Thanks

RE: Thread Specification
Regardless of which countries spec you use they should all more or less conform to the ISO, kind of the point.
Ideally what spec it is to should be on the drawing, at least this is how it's meant to be done in the US.
