Studs like this thread into the casting on one end and take a nut on the other, letting a cover or mating case be drawn down evenly without the stud itself turning. Beyond its place in the crankcase drawings, our records don't give more detail on length, thread, or exact mounting position.
If you're replacing one, it's worth checking it against the original before you order, since crankcase studs can vary in length and thread depending on where they sit in the casting. Call the shop and we can help confirm which one you need.
