Well, I'll admit I didn't take a TR6 apart to check, but I did check 2 different
versions of the TR6 factory SPC (Spare Parts Catalog), a Vitesse SPC, a 2000
sedan SPC, and the TRF TR6 catalog. All 5 sources list the pan bolts as P/N
HU0805, which according to the Standard-Triumph Hardware Catalogue is a 5/16"
UNF Hex head setscrew (which in British parlance means it's threaded all the
way), 5/8" long. My GT6 SPC lists HB0805, which is a bolt rather than a
setscrew, but still 5/16" UNF by 5/8" long. Both Vitesse 1600 and GT6/Vitesse 2
liter workshop manuals also specify 5/16", tightened to 16-18 ftlb (sorry don't
have TR6 workshop manual yet).
And I think I would have remembered if the pan bolts took a 9/16" socket rather
than 1/2", as there are so few 3/8" fasteners on a Triumph.
