Norton Nut, Self Locking
A 5/16 UNF self-locking (nyloc) nut used in the fuel tank and fittings group.
This is a self-locking nut that shows up in the fuel tank and fittings section of the parts book, used to secure fuel tank hardware. It's a nyloc-style fastener with a nylon insert that resists vibrating loose, which matters for a part sitting near the fuel tank mounts where rattling loose is not something you want.

Our catalog record only ties this one to a single appearance, in the Fuel Tanks and Fittings group. The listing elsewhere shows it as a 5/16 UNF nyloc nut, which lines up with what a fuel tank fitting nut would typically need.
If you're matching this against an old tank strap or mounting bolt, check the thread on your existing hardware before ordering — call the shop and we can confirm fitment.
