Studs like this take a beating from repeated cover removal for valve adjustments, and threads can pull or gall over the years, so it's worth checking the condition of the hole it screws into as well as the stud itself before you button things back up.
We don't have much more detail on file for this one beyond the basic spec. If you're not sure this is the exact stud your rocker cover needs, give us a call and we'll confirm before you order.
