Looking for a few M6 (10mm) nuts.

Where all can I usually find them on a Honda.
I got a parts car Civic sitting around.
No motor, so valve cover nuts are out.
Any where else?

Looks like I'm late to the party, but, I got one... What is the bolt spec for the Camshaft Position Sensor on 01-05 Civic? I seem to have dropped mine...into the LCA. Makes things a little tricky.

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:
https://honda-tech.com/zerothre...54427

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
M16-???
M20x1.0 -- 10mm allen bolt
M20x1.5 (oil filter threads????)
M22x??? d-series countershaft nut
M28x1.5 - 14mm allen bolt

A 10mm headed bolt is typically a 6mm x 1.0 pitch bolt thread.

I'll get back to ya about the 17mm head suspension bolts
How long are the bolts typically? I seen M6-1.0 x 12 MM on Amazon. Redoing my engine bay looking to replace with brand new bolts

They vary depending on the location of the bolt. I have trays and trays of Honda bolts and I have to match up length anytime I'm replacing one with one I kept from the Salvage yards. There is no one default length on any of the sizes of bolts.

In example, even the flywheel/flex plate bolts are different lengths. The automatic has shorter bolts while the manual has a bit longer bolts. Water pump has 3 shorter bolts and 1 longer bolt or vice versa.

Really, the only way to get the right bolt is to order it from Honda if you are after brand new.

Would anyone happen to have the thread pitch and bolt size for the oil pan? Not the drain plug, but the other bolts. I’ll be replacing mine with the gasket and would like to put new bolts in.

Default Re: Common Honda Bolt thread pitch size dimension

I have actually spent a fair amount of time on this subject over the last few months. I hit my breaking point earlier in the year when I spent way too much time in my garage looking for an M10x1.25 nut. Since then I have ordered packs of washers and nuts that are most common to what Honda uses. In addition to that, I have ordered ones that are the same width, and that also have their flange nuts.

Here are the sizes, along with the McMaster-Carr part numbers. The first 4 parts are ones that are most common. All of these have heads that are the same width as what Honda uses. If you're like me, you can't stand when a nut that you normally use a 12mm socket on, requires a 13mm. So I've made sure that there's no funky crap in here (i.e. 11mm, 13mm, 15mm, 16mm, 18mm, etc)
M6x1.0 - 10mm - https://www.mcmaster.com/95108A107/
M8x1.25 - 12mm - https://www.mcmaster.com/95108A103/
M10x1.25 - 14mm - https://www.mcmaster.com/95108A105
M12x1.25 - 17mm - https://www.mcmaster.com/95108A104

I have had a few instances where I've needed an M14x1.5, so I'm adding these two.
https://www.mcmaster.com/4391N117
https://www.mcmaster.com/95003A214

Obviously, these aren't the only possible options. Additionally, you should know that Honda uses distorted thread lock nuts for things like suspension fork bolts.
