Please help me fill in the blanks and or correct me if I'm wrong. Honda uses some weird sizes. I had to specially order a M14-1.5 nut for example. Also, do they all tend to share the same thread pitch? I see M12-1.25 and M12-1.5. I searched for "thread" and got 750 results, I'm not about to sort through 750 threads. I searched for "thread pitch" and it returned 97 results, most of them pertained to specific bolts

See this guys post:

M6-1.0 --- common (most of our 10mm head bolts)
M8-1.25 -- common (probably most of our 12mm head bolts)
M10-1.25 - some headbolts) (probably most of our 14mm head bolts)
M11-1.25 - freakshow timing belt tensioner on H/F engines. 7/16-20 is VERY close.
M11x1.5 -- some headbolts)
M12x1.0 -- flywheel bolts + shift fork ball spring bolts)
M12-1.25 - common (probably most of our 17mm head bolts)
M12-1.5 -- lugnuts)
M14-1.25 - crank bolt?)
M14-1.5 -- oil pan drain plug. 19mm head bolt that connects rear trans bracket to trans

M18x1.5 is the O2 sensor bung 1/8 BSPT is the oil pressure sensor threads

Also, if it's an unusual thread, like the oil filter for example, Please put it like this
M20x1.5 (oil filter threads)

you caught me before I could edit it

I believe that most of our M8-1.25 bolts are what we use the 12mm sockets for. However most of the nuts/bolts that we buy in conventional hardware stores that are M8-1.25 use 13mm heads. I just need to verify that 1.25 is the common thread pitch.
