NUT 7/16X26 THIN SPINDLE (1/4 thick)
This is a thin spindle nut, 7/16 x 26, listed at 1/4 inch thick. Triumph's parts books place it in the FRAME COMPLETE and FOOTRESTS/CHAINGUARD/PROPSTAND figures, which puts it in the wheel spindle or stand-pivot hardware family rather than anywhere in the engine or gearbox.

The legacy H193 stamping and the M97-0193 form are the same physical nut under different catalog numbering, so if your parts book shows either of those, you're looking at this same piece. Catalog appearances tie it to the 1963-1964 span in our records.
It's a small, easy-to-overlook piece of hardware, but the kind of thing worth having on hand rather than making do with a substitute nut that doesn't match the thread and thickness. Call the shop if you want us to confirm exactly which spindle or stand application your bike uses it on before you order.
