ROCKER NUT STAINLESS 3/8
Stainless 3/8 inch dome nut for the rocker spindle on the head.
This is a 3/8 inch dome-style rocker nut, made in stainless, that fits on the rocker spindle up top on the head. It's the acorn-shaped nut that caps off the rocker spindle, and it's a small part but one owners like to have in stainless so it doesn't rust or pit over time sitting out in the weather.

The part number carries an S suffix here marking it as the stainless version, with 21-0550 as the base number for the same nut in other finishes. If you're pulling the rocker box apart for a valve adjustment or a top-end job, this is worth checking while you're in there since these small fasteners get chewed up by wrenches over the years.
