Cap bolt (1 3/8 in. U.H.)
A 1 3/8 in. under-head-length cap bolt used across multiple Triumph fork, fittings, and cover assemblies.
This is a cap bolt, 1 3/8 in. under head length, showing up across a wide range of Triumph catalog figures from the front fork assembly to fittings around the motor unit, footrests, and side covers. The 1 3/8 in. U.H. dimension is called out right in the parts book description, so that much you can count on. Where any given one lands depends on which figure you're working from — this number turns up in fork-spindle related figures as well as several unrelated fittings figures, so don't assume it's a fork-only bolt just because that's where a lot of the listings put it.

The older factory number for this one was 21-0644, so if you're working from an early parts book and see that number, it's the same physical bolt under the earlier numbering.
Given how many different assemblies call for this cap bolt across the catalog span, it's worth having a few on hand — the length is fixed at 1 3/8 in. U.H. but confirm which application you're ordering for before you commit, since the fitment isn't tied to one single job.
