Norton Nut, Crankshaft Stud
A nut for a crankshaft stud in the engine bottom end, per a single 1975 catalog listing.
This is a nut that fastens onto a crankshaft stud down in the bottom end of the engine, holding parts of the crankshaft assembly together where it appears in the crankshaft, connecting rods, pistons, camshaft, and timing gear section of the parts book. The catalog record we have for it is a single one-year listing, so we don't have much more to go on beyond the basic description.

We don't have details on thread size, material, or which specific engines it was fitted to beyond what's in that single catalog entry. If you're trying to match this up to a rebuild, bring in the stud and old nut if you have them so we can check the fit before ordering.
Given how thin our record is on this one, treat it as a lead rather than a confirmed match — call the shop and we'll help nail down fitment before you order.
