BSA Screw, outer cover (2 British Association × 5/8")
A 2BA x 5/8 inch outer cover screw used across several electrical and gearbox-area figures on 1969-1972 Triumph/BSA models.
This is a small fastener, a 2BA by 5/8 inch screw that shows up in the parts books under electrical equipment, footrest and footchange, and gear cluster figures. The 2BA thread is the old British Association standard, common on Triumph and BSA electrical covers and small castings from this era.

With it turning up across several figures, this looks like a general-purpose screw the factory used wherever an outer cover needed securing, rather than one part carrying a single dedicated job. The catalog record ties it to appearances between 1969 and 1972 across those figure groups.
If you're chasing one of these down to replace a stripped or missing screw, check the thread size against what's in your cover before ordering, since 2BA doesn't interchange with modern metric or UNF hardware.
