Nut
A 10-32 UNF nut used on the exhaust pipe clamp hardware on unit 750 Triumph twins; some suppliers cross-reference it to 97-0745.
This is a small nut, PN 21-7009, that shows up repeatedly in the exhaust hardware for the unit-construction 750 twins. The catalog places it in the exhaust pipes and mufflers figures for the T140V and TR7RV, and it's threaded 10-32 UNF, which is the size used with the finned exhaust pipe clamps on these bikes rather than a big fastener.

It's the kind of nut you don't think about until you're missing one at the workbench and the clamp won't cinch down. Since it turns up across ten catalog listings spanning 1976 to 1985, it's clearly a part Triumph used in quantity on the exhaust system rather than a one-off.
Some supplier catalogs cross-reference this number to 97-0745, so if you're working from a newer parts book or a shop lists it that way, check it against your book or call us before ordering.
