Norton Mute Screw
A small screw used with exhaust mute/muffler hardware, per the parts book listing.
This is a mute screw, a small fastener that shows up in the exhaust and muffler section of the parts books. The figure titles it appears under cover exhausts, mufflers, mutes, and passenger footpegs, so it's tied to the exhaust/muffler hardware rather than anything electrical, even though it's filed under a Lucas-style number in our records.

Beyond that we don't have much more detail on this one. The catalog listing is brief and doesn't spell out thread size, material, or which side of the bike it goes on.
If you're trying to match this up to a specific muffler or mute assembly, give the shop a call with your bike's details and we'll confirm fitment before you order.
