Norton Bolt, Banjo
A banjo bolt from the oil system area of the engine, used to join an oil line fitting while allowing oil to flow through its center.
This is a banjo bolt, listed in the catalog under the oil system side of the engine, in the same group of figures as the contact breaker, timing cover, oil pump, and oil pressure relief valve. A banjo bolt like this is a hollow-center fastener that lets oil pass through its bore while it clamps a banjo-style fitting down onto a mating face, so it's doing double duty as both a seal point and a structural bolt.

Our catalog record only shows this one turning up once, tied to a 1975 model year, and the description doesn't spell out which specific oil line or feed it serves beyond sitting in that oil-pump/relief-valve area of the engine. Given how banjo bolts are used elsewhere on these engines, it's a fair bet this one is carrying oil to or from a specific gallery, but we don't have that nailed down in our records.
Before you order, it's worth double-checking this against the oil line or fitting it's meant to join on your particular engine, since banjo bolts vary by length and by the size of the union they pass through even when they look similar on the shelf.
