Bolt, lamp fixing (99-1004)
Headlamp shell fixing bolt for Triumph unit twins, listed as 112201 and under the earlier 99-1004 number.
Part number 112201 is the bolt that fixes the headlamp to its shell brackets, listed in the older parts books under 99-1004. It shows up across the ignition capacitor and headlamp figures for the T100C and TR6C, as well as in the wiring harness and direct lighting sections, which is where these lamp fixing bolts tend to get filed even though they have nothing to do with the electrics themselves.

This is a small, easily lost bit of hardware, and it's worth having a spare or two on hand since it's exactly the kind of fastener that walks off during a headlamp shell swap or a wiring job. Catalog appearances for this number run from the mid-to-late 1960s into 1970.
If you're chasing this by the old book number, 99-1004 and 112201 are the same physical bolt in our records, so either number will get you to the right part.
