Plain washer (70-2351)
A plain washer (also listed as 70-2351) used across various Triumph ignition and electrical hardware mounts.
This is a plain washer, catalog number 131023, with a legacy cross-reference of 70-2351. It shows up repeatedly across ignition and electrical figures in the parts books - timing cover and contact breaker assemblies, ignition coil mounting, horn, rectifier and zener diode setups, and even alongside the headlamp on T100C listings. That spread tells you this is a general-purpose hardware washer that Triumph used wherever a bolt or stud needed a simple spacer or seating surface in the electrical system, not a washer built for one specific job.

Because it turns up in so many different figures across a wide span of years, treat it as generic small hardware rather than something tied to one bracket or one component. If you're chasing a washer for a specific coil, rectifier, or contact breaker mount, it's worth double-checking your parts book figure against the ones listed here to make sure the fit and washer size line up before you order.
We don't have more detail on this one beyond its appearances in these ignition-and-electrical figures - no stated size, material, or finish in our records. Call the shop and we'll help confirm what you need for your particular application.
