Norton Screw
A general-purpose screw appearing in oil system and rear fender/tail light catalog listings, PN 22403.
This is a screw, listed plainly in the catalog under part number 22403. It shows up across a couple of different figure groups in our records - one covering the oil tank, oil pipes, junction block, rear chain oiler and full flow oil filter setup, and another covering the rear fender, tail light and tail section. That spread suggests it's a general-purpose fastener rather than something tied to one specific bracket or assembly.

Because the catalog entry is just "Screw" with no further detail, we don't have thread size, length, or material on file for this one. The manufacturer tag on our records says Lucas, but a plain screw showing up in oil system and rear fender/tail light figures doesn't line up with what Lucas actually made (electrical parts), so take that tag with a grain of salt.
Given how little detail comes through in the catalog listing, your best bet is to call the shop with the exact location you're trying to fasten - oil tank hardware or tail section hardware - and we can help nail down which screw you actually need.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
