3/8X26 NYLOCK NUT
A 3/8x26 nylock nut with a nylon thread insert to resist vibration loosening.
This is a 3/8x26 nylock nut, a fastener with a nylon insert built into the threads to keep it from working loose under vibration. The catalog entry is brief and doesn't tie it to a specific figure or bike area, so we can't say exactly where it's used on your machine, but nylock nuts of this size turn up in various spots where a standard nut would otherwise back off over time.

The part also shows up under the number NB197 in older listings, so if you're cross-checking against a different parts book or an older supplier reference, that's the same nut.
Give the shop a call if you want to confirm this is the right nut for your application before ordering — with so little written down on this one, it's worth double-checking fitment.
