need a mysql delete query

I have table that has well over a million entries and need a query to remove a lot of entries in one go. Every entry is linked to a specific thread. What I need to do is remove all those entries where the last entry in that thread was before a specific time. The query I use to identify those entries is as follows:

select thread FROM board group by thread HAVING MAX(addedon) <'1546300801'

I now need the mysql routine to delete all those entries associated with those threads.
