Screw
A small Triumph screw (97-0688) used in gearbox inner cover work and nacelle/headlamp switch assemblies.
This is a small screw carried under Triumph part number 97-0688, also seen in older parts books as 97-688 or H688. It shows up across a wide run of catalog entries from 1960 through 1974, which tells you it's one of those general-purpose fasteners the factory used in more than one spot rather than something built for a single job.

The catalog listings tie it to gearbox inner cover and shaft work, and separately to the headlamp nacelle and switch assembly, with another appearance on the T20 telescopic front fork listings. That spread is common for a small screw like this one - the same size and head style got specified wherever it fit, whether that's holding down a gearbox component or securing switchgear inside the nacelle.
Because the catalog description itself is just "Screw" with no further detail, we can't tell you head type, thread, or finish with confidence from our own records alone. If you're matching one for a specific job on the gearbox or the nacelle, bring the old one in or give us a call and we'll help you sort out the right one before you order.
