BSA Screw, inner plate to centre (1 British Association × 35/64" countersunk)
Countersunk 1 BA screw, 35/64 inch, that fastens the inner clutch plate to the clutch center in the primary chaincase.
This is the small countersunk screw that secures the inner clutch plate to the clutch center, as shown in the clutch and primary chaincase figures. It's a 1 British Association thread, 35/64 inch long, countersunk head - a fastener spec straight out of the parts book rather than a common hardware store size.

Because it lives inside the primary chaincase, it doesn't take much abuse once the clutch is assembled, but it's exactly the kind of small part that walks off during a clutch strip-down or gets replaced with the wrong thread by mistake. Worth having a couple on hand before you open up the primary side.
