Bolt (1 1/4 in. U.H.)
A 1 1/4 in. U.H. hex bolt used in exhaust pipe, silencer, and undershield assemblies.
This is a bolt from the exhaust hardware catalog, listed at 1 1/4 in. under head. It's turned up across a wide run of exhaust pipe and silencer figures over the years, including on T100C undershield and footpeg setups and on T120R/TR6R exhaust pipe and muffler assemblies, so it's the kind of small fastener that gets used more than once holding pipes, silencers, and related brackets together.

The legacy alias for this one is F3430, so if your parts book is older and lists that number instead of 82-3430, you're looking at the same bolt.
It's not an expensive item, but exhaust bolts take heat and vibration over the years, so it's worth checking the one you've got for stretch or thread wear before you decide you just need a gasket or clamp instead.
