My nursery told me to think about the hitting and screaming as him saying Mum, help me, I don't know how to behave in this situation right now.... And that cltotally changes how I think about the situ. I also grab my daughter by the wrists when she does it and say to her: Mommy loves you sooo much, but if you continue to hit me, you are CHOOSING to hurt me. That usually stops her in her tracks. Best of luck
Try empathising- he doesn’t have the words yet. Help him name his feelings like ‘you sound very cross right now’ or ‘you look like you have some big feelings happening do you want to tell me about it?’

I often find that when my son is having a screaming/ hitting match, if I ask him if he wants a hug he will cry and give me a cuddle then we can move on ☺️
