Nyloc nut
A Nyloc self-locking nut, PN 82-9085, used at several pivot and mounting points including footrests, swinging arm, and rear wheel.
This is a Nyloc nut, catalog number 82-9085, also known by the older alias F9085. It's a self-locking nut with a nylon insert that grips the threads so the nut won't work loose from vibration, which makes it a common choice anywhere on the bike that sees constant movement or shaking.

The catalog shows this nut turning up in footrest and brake linkage assemblies, on the swinging arm, and at the rear wheel, so it's a general-purpose fastener used across several points where things pivot or bolt together under load. Appearing in eight catalog entries across 1968 to 1970 records tells you it got used in more than one place on the bike rather than being a one-off part.
If you're replacing one of these, match it up against where it came out - footrest mounting, swinging arm pivot, or rear wheel area - and check thread size before ordering, since these nuts differ by the bolt they're paired with.
