threads per inch or mm. In otherwords pitch determines iof the thread is fine or coarse for a filter.

As you can see here (http://www.heliopan.de/Preisliste.pdf) on page 6 filters 40.5 are only aviable with the pitch you need for your Xenar 150mm.

Have fun

It'll be a Compur 1 or a Copal 1 as it's quite an old lens approx 1967.
