M10x1.25 Threaded Rod - Unobtainium??

[Dr. Frankenstein]

I have searched high and low for some M10x1.25 fully threaded rod about 200mm in length (8 inches or so) for a project I'm working on and cannot find it anywhere! There's tons of M10x1.5 threaded rod available for a reasonable price, but for some reason M10x1.25 is unavailable in the States, or hugely expensive.

Conversely, a full METER of M10x1.5 threaded rod as sold on the Grainger website is about $3.50...they don't have M10x1.25...

Meanwhile, ONE piece of 200mm (8") of M10x1.25 threaded rod imported from China (on Ebay) is $30!

What gives??

Buy it from China if your in no rush or keep looking in the US. Making your own from a bare metal rod and a die is also an option if you can’t find it.

McMaster Carr has it.
$18.86 for 300mm

I was just going to say, McMaster Carr would have it…may not be cheap, but they seem to have a lot of stuff!

[Dr. Frankenstein]

Yes, but what the heck makes THAT thread so expensive? I may just have to make my own.

If you decide to try making your own, I suggest watching this review videohttps://youtu.be/lE346z7HOnk. He makes threaded rod in it, and several of the dies rapidly failed.

Well after watching that video the $18 threaded rod looks pretty cheap. Buying a decent die will set you back way more than the price of the threaded rod alone.

Coincidentally (and for a bit of useless trivia) the mirror mount threads on the clutch perch and front brake master/perch are M10-1.25.
Of course that isn't so useless if you happened to have changed your mirrors and are trying to locate a chrome bolt to just fill the damn hole!

I have never found any threads on a Honda to be "coarse thread" whatever the diameter; it's always the finer pitch. And the hardware metric bolts are usually coarse. I would imagine it's a JIS/ISO thing.

Dr. Frankenstein » what do you want to do with this rod? Maybe some one else has a solution. To answer your original question, "Why does it cost so much?" Look around, everything is being affected by inflation...

Good luck with your project.

Later, Bud...

I am going to try to take out the long head bolts - which are M10x1.25 but only threaded on the far ends, deep in the block - and reinsert the threaded rod with some nuts on them to try to 'jack up' the heads off the frozen pistons. Alternatively, since the pistons have been soaking for a while now, I also have a drive chain coming with which I intend to put on the bike and rock back and forth to see if I can't get the drive chain to loosen up the pistons to hopefully slide them out, or at least give me enough room to get underneath the head. The bike is currently frozen in gear and won't shift either. She's locked up good and tight.

Pricewise, if you go looking at all the threaded rod out there it's all M10x1.5, and that can be found for $3.50 per METER!

Even from China on Ebay, for instance, the M10x1.25 threaded rod still averages about $20 per 250mm (about 9 inches); the McMaster-Carr link that somebody sent me does have the M10x1.25 threaded rod, but that too is $18.80 per 8 inches!

So, it IS available, but I need at least four sections of it that is at least eight inches long to be able to jack up the head evenly; I'm just wondering what it is about that thread size that makes it so expensive. Every other thread size out there is cheap enough, but for some reason M10x1.25 is hard to come by, and expensive.
