BOLT 5/16 UNF 1 1/8UH
A 5/16 UNF, 1 1/8 inch under-head bolt used across frame, exhaust, and footrest mounting points.
This is a 5/16 UNF bolt, 1 1/8 inch under the head, showing up across a handful of different jobs on the bike rather than one dedicated spot. Our catalog data has it turning up on frame assembly work, exhaust pipe and muffler mounting (including the TR6C exhaust setup), and motor unit fitting and footrest hardware. It's the kind of general-purpose fastener that shows up wherever a 5/16 UNF thread and that specific length are called for.

Because it crosses so many different assemblies, don't assume it's the exact bolt for your particular application just because you found it under one figure - check the length and thread against what's actually in your hand before you order. The catalog spans a good stretch of the 1970s, which fits with it being a common hardware item rather than something tied to one model year.
If you're rebuilding a section of frame, sorting out exhaust bracket hardware, or putting footrests back on, it's worth having a few of these on the shelf.
