Nut
A small hex nut used in crankcase assembly, listed in the 1968 parts book under 70-8042 (earlier form E8042).
70-8042 is a nut that shows up in the crankcase section of the parts book, listed against 1968. The catalog description is just "Nut," and the crankcase figure it appears in doesn't spell out exactly which fastener location it covers. It also carries the earlier E8042 form, which is just the pre-1968 style number for this same part.

Because the record here is thin, we can't tell you the thread size, hex dimensions, or which specific stud or fastener it threads onto without pulling the figure and cross-checking your engine. If you're chasing a small hex nut for crankcase hardware and this number matches what's printed in your parts book or on the old part, it should be the right one - but call the shop or bring in the old part to confirm before you order.
Given how little detail the catalog gives us on this one, treat it as a straightforward small hex nut for crankcase assembly work rather than anything with special specs, and double check fitment against your actual engine before installing.
