This is the clutch spring pin, 1/4 inch British Standard Cycle by 1 3/4 inches long, shown in the clutch and primary chaincase figures. It's one of the small threaded pins used with the clutch springs on the primary side of the engine, and it turns up in the parts book across several years running into the early 1970s.

If you're rebuilding the clutch assembly or chasing down a stripped or bent pin, this is the one the book calls out for that job. Given its size, it's the kind of small hardware worth keeping a spare or two of on the shelf when you've got the primary cover off anyway.
We don't have more detail on this one beyond what's in the parts book listing, so if you're not sure it matches what's currently in your clutch, give us a call and we'll confirm before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
