Common bolts = common thread pitch? (1 Viewer)

[ThunderRolls]

I wanted to throw a few spare bolts in my cruiser stash for emergencies or lost bolts. In looking through a couple of solo cups of bolts from cruisers I've had, it occurred to me to look here and see if the common sized bolts all had the same thread pitch or not. (various lengths)

The only thing I could really determine on searching was that most are 1.25 pitch:
(restated by head flat to flat)

10mm head - 6mm bolt x 1.0p
12mm head - 8mm bolt x 1.25p
14mm head - 10mm bolt x 1.25p


Any other info for my "misc bolt emergency stash?" I'll be glad to update the thread if people want to add different sizes and lengths if you want me to keep it all in one place.

EDIT: I'm not trying to list every single bolt like a M14 x 1.0 used on one item on the truck)

Toyota uses JIS fasteners. They usually have a small head in comparison to thread diameter.
There's also a handful of fasteners that will use a fine pitch thread.

Ok, I'll rephrase above. Question about pitch remains the same.

They use the 'fine pitch' version of whatever size you need, except for the high strength areas that use the ultra fine pitch(tow hooks, etc)

The 6mm size bolts would be a 1.00p.

Most replacement bolts you get locally will have a different size head on them, unless you specifically order JIS sized bolts.


Or buy a partstruck.

The majority of fasteners are 1.25 thread pitch throughout the vehicle.

6x1.0, 8x1.25 10x1.25 are going to be your most common and those would be 10mm, 12mm, 14mm

Great little tip is if you can find a truck in the salvage yard you can grab a lot of different size bolts for next to nothing.

Protip: All Japanese cars will use the same hardware.

Thanks for the confirmation. I have a few cups of bolts from three cruisers through the years and thought I would sort a small bag to put in the rear "just in case" but didn't want to run into that infamous "first time I've seen that sh!t" moment and not have THE right bolt or nut. I think I have it covered, but never hurts to search all the threads and ask a questions - and then spend $5 at the store next time I'm there

Thanks guys!

I've always referred to these Toyota guidelines for hardware....

Think @beno covered it

 

[ThunderRolls]

WOW! Just what I didn't know I needed and more! LOL! Thanks @beno!

@beno That right there is pure Gold, thanks!

So, let me get this straight. . . In the metric system, everything is a nice round number? Bigger numbered bolts are always bigger than smaller numbered bolts? WTF? Where's the 11/16th?

Off the top of their head, does anyone know the bolt specs for the 3rd row seat brackets.
