This is a 5/16 inch U.H. screw that shows up in the carburetter and float chamber assemblies on the catalog pages for the 6T, T110, TR6, and Bonneville 120 models. It carries the older E4054 number in earlier parts books before being listed as 70-4054.

Being a fastener that lives right on the carb and float chamber, it is one of those small parts that is easy to lose track of when you have the carb apart on the bench. Worth checking the condition of the one you pull before you decide whether to reuse it or drop in a fresh one.

The catalog entry itself is brief beyond noting the size and where it turns up, so if you are trying to match this against a specific machine, have the carb in front of you or call the shop and we will help confirm fitment before you order.
