Self-locking nut
A self-locking nut used across numerous mounting points on Triumph unit twins, including mudguards, forks, and swinging arm hardware.
14-0702 is a self-locking nut that shows up all over the catalog record, from mudguard mounting to swinging arm suspension units to front forks and the chaincase area. It's a general-purpose fastener Triumph used in a lot of places rather than a part tied to one job, which is why you'll find it listed under so many different figure titles across the years.

The self-locking design means it holds its own tension without a separate lock washer, which is handy in spots that see vibration - fenders, forks, footrest and brake linkage mounts, and so on. Given how many places this nut turns up in the parts books, it's worth keeping a few on hand rather than hunting one down mid-job.
You'll also see this same nut listed under 14-702, 14.0702, 140702, and similar formatting variants - all the same physical part, just written differently across old catalogs and microfiche.
