I was able to pick up some replacements of the correct size in stainless with socket head or hex head at my local hardware store, however I could not find ones with Torx/Black Oxide
they are M8x1.25, the shortest ones are 30mm, the longer ones are 40mm and 45mm IIRC

EDIT: it looks like McMaster-Carr has exact ones, but at the time I wanted to get some on that same day in person.
