Clamp bolt
A clamp bolt from the gearbox outer cover area, Triumph part 57-1439 (formerly T1439).
This is the clamp bolt listed under Triumph part number 57-1439, with the older parts-book form being T1439. Catalog records place it in the gearbox outer cover and levers section, which fits with its job as a clamp bolt for one of the lever fittings on that cover, and it also turns up in listings for U.S.A. exhaust pipes and mufflers.

Because it shows up across both those figure groups, the exact spot it clamps down on isn't nailed down from what we have on file. If you're chasing this one down for a rebuild, have your parts book open and match the figure and item number before you order, since a clamp bolt like this can look similar to several others used elsewhere on the machine.
It appears across a run of catalog years from 1964 to 1968, so if your bike falls outside that span, give us a call and we'll confirm it's the right one before you commit to it.
