BSA Oil drain screw
An oil drain screw for the primary chaincase.
PN · 21-1856
This is an oil drain screw that lives in the primary chaincase, per the catalog record where it turns up. It's the fitting you'd pull to let the primary chaincase oil out for a change rather than a screw for the engine or gearbox itself.
