Norton Nut, handrail to support rail (5/16" British Standard Cycle)
A 5/16 inch BSC nut used at the handrail-to-support-rail joint, also seen across other frame-area fittings.
PN · 02-0049
This is a 5/16 inch British Standard Cycle nut, listed in the catalog as fitting where the handrail meets the support rail. It shows up across several frame-related figures, including frame, engine shield and battery carrier, front forks, and mudguards, which tells you it's a general-purpose small nut used in more than one spot rather than a single dedicated fastener.
