Nut
A 3/8 inch UNF thin nut used across dozens of clutch, brake, gearbox, and frame assemblies.
This is a 3/8 inch UNF thin nut, catalog number 14-0403, one of the most widely used fasteners across the parts books. The listing shows it turning up in dozens of figures — clutch and primary chaincase, cylinder and crankshaft, engine fittings and footrests, frame, front and rear brakes, front forks and steering head, gearbox, and the hydraulic brake groups. That spread tells you this is a general-purpose nut rather than something built for one job; wherever a stud calls for a slim 3/8 UNF nut, this is likely the part on the page.

The earlier factory numbers 13206/00/1 and 60-4180 cover this same nut, so if your parts book lists either of those, you're looking at the identical fastener under an older reference. Given how often it shows up across clutch adjusters, brake components, and mounting hardware, it's worth keeping a handful in stock rather than chasing one down mid-job.
Because it appears in so many different assemblies across a long catalog run, don't assume every 3/8 UNF nut on the bike is this exact one — check your parts book against the specific figure you're working from to confirm it's the right fastener for that spot.
