He didn't inscribe INRI, those are the first letters of each word that he inscribed. The phrase in Latin was: "Iesvs Nazarenvs Rex Ivdaeorvm."
Which is Jesus of Nazareth King of the Jews.
What's more incredible is how the Hebrew looked which is why the Jews were so upset:
The Yod Hey Vav Hey as you said!

Dear Pastor Mark
When Pontius Pilate crucified Yeshua, he scribed INRI as a testimonial above the Lord Yeshua's head. Did he also scribe Jod He Vau He?
What else was written?
