This is a tappet adjuster nut sized 5/16 CEI thread with a 7/16 SAE hex head, part number 70-0470A. It's the locking nut that sets and holds tappet clearance on the valve gear, threading onto the adjuster screw so you can lock in your gap once it's set.

The catalog lists it under the alternate form 70-0470 7/16 HE as well, so if your parts book or an old invoice shows that number, it's the same nut.

We don't have more detail on this one beyond the thread and hex spec noted above. If you're matching an original tappet adjuster setup, call the shop and we'll confirm fitment before you order.
