‘Spire’ nut
Captive 2BA spire nut that holds the Triumph side panel nameplate badge screw in place.
This is the small spire nut Triumph used to hold the side panel nameplate in place, part number 60-4154. It's a captive nut, meaning it sits pressed into the side panel tin itself rather than floating loose, and it's threaded to accept the 2BA screw that runs through the metal badge on the panel.

Because it's captured behind the tin, you don't have to fish around back there trying to hold a nut steady while you thread the badge screw in from the front — the panel does that job for you. It shows up in the catalog under the AIR CLEANER AND SIDE PANELS listings, so if your nameplate boss has torn loose from the tin or the nut has spun out, this is the part that restores it.
Catalog appearances for this one run 1974 through 1977. If you're not sure your side panel takes this exact captive nut, bring the panel in or give us a call before ordering.
