Got my clutch changed at a shop and not only did they damage my knock sensor but they forgot to put this bolt in...

I need help identifying what it is called so I can order one from Honda or just Home Depot

its driver side near the tranny and engine

Also, does the knock sensor look broken? I couldnt get a tool to take it out just my camera

THANKS!
