Also, the water pipe on the side of the head that gives water to the heater valve is M20x1.0

MAP sensor bolts M4x.7
Small bolts that hold down the fuses in the underhood fusebox, and also the battery and starter leads are M5x.8

Andddddddd the oddest nut I think!

The throttle rotor nut, M6x1.0 with an 11mm head

additionally (if it hasn't been posted yet):
you can find OEM bolt LENGTHS on many of the honda/acura parts websites as honda lists them by diameter and length

-Fuel Rail
-Shift Linkage

Power of Dreams · 11-30-2007, 09:54 PM

Looking for the thread, pitch, and length (if you know that also) for the camshaft gear retaining bolt on a D15B7 engine.

I believe it's M8 x 1.50. That's what I measured with the pitch gauge, but because the bolt was snapped in half near the shoulder of the head, I couldn't get a very accurate measurement.

Help is greatly appreciated.

Thanks.

This brings up something else. Although factory 10mm bolts use a 14mm head, 10mm bolts purchased at a hardware store generally use a 17mm head. And while factory 12mm bolts use a 17mm head, 12mm bolts purchased at a hardware store use a 19mm head. I am not sure why this is. But while this is not a problem most of the time, I have run into situations were the larger head caused fitment issues.

Mikey3000 · 01-04-2008, 03:31 PM

Because I don't see the H series head bolt.

M12 x 1.5 mm x 185 mm long. The head is 14 mm.

JDM JEFFREY · 01-08-2008, 06:57 AM

I need the thread size for the 17mm bolt that hold the tranny to the block.

ClemsonS197 · 02-01-2008, 07:27 AM

Noob here not in the Honda world, but I'm having a heck of time finding a set up nuts. I need a M14-1.5 flange nut, and a M12-1.25 flange nut.

I came across this thread and saw:

"Subframe flange bolt: 14x1.5mm"

Is there a flange nut for the other end of that? Can someone tell me how I can get a local Honda dealer to find these parts? Car, year, model, etc? Thanks in advance.

draperj09 · 02-03-2008, 07:59 PM

Boosted Rex · 02-14-2008, 02:26 PM

DIRep972 · 02-18-2008, 07:55 PM

I am having to re-calibrate my tps sensor by changing the position. Basically the stock rivit screws that I have with cut ends aren't giving me any leverage. I tried to use the map sensor bolts and they did not thread all the way in.

Anyone know the thread/pitch? thanks
