Self-locking nut
Self-locking Philidas-style nut for the stator studs on early unit-construction Triumph twins.
70-5324 is a self-locking nut used in the chaincase area, specifically on the stator studs of early unit-construction Triumph twins. It's a Philidas-style nut with a locking ring built into the top, which keeps it from working loose under the vibration these engines put out. Being a thin nut, it's made to fit into tight clearance where the alternator stator sits close to the case.

The legacy number on this one is E5324, so if your parts book lists it that way, you're looking at the same nut. It shows up across chaincase and chain figures in the catalog through the mid-to-late '60s.
When you're pulling the stator for inspection or replacing the wiring, these nuts are worth replacing if the locking feature looks worn out or if the nut won't hold torque anymore. Since they're specific to the stator mounting, keep the count straight when you pull them so you don't come up short on reassembly.
