Shakeproof washer, capacitor pack to platform
A shakeproof washer that secures a capacitor pack to its mounting platform on Triumph electrical assemblies.
GS299 is a shakeproof washer used to secure a capacitor pack to its mounting platform on the bike. It's a small hardware piece, but it shows up across a huge span of the catalog because Triumph used this same washer in dozens of electrical assemblies over the years - anywhere a capacitor pack, coil, rectifier, or zener diode needed a secure mount, this washer likely turns up in the parts list alongside it.

The wide range of figure titles this part appears under - timing covers, nacelles, headlamp assemblies, mudguards, and more - reflects how many different electrical sub-assemblies used the same basic hardware, not that this one washer does all those jobs at once. If you're chasing down a specific assembly, check your own parts book figure to confirm GS299 is called for in that spot.
This number was later superseded by 60-4256, so if your bike's build sheet or a more recent parts list calls out 60-4256 instead, that's the same washer under its current factory number.
