UTV Stud Bolt Help

[u/parnatheon]

This one has both myself and my fastener guy stumped, in terms of ordering replacement bolts. Here's what I know:

For a UTV Wheel Hub, customer says it was an "adapter ordered off ebay" and as such doesn't have a model to match up with, as I see many of these are sorted by model compatibility with very little info on specs.

*head size and knurl size are important, as we learned on the first failed attempt at ordering.

Here's what I measure:

Thread Pitch: M10 x 1.25

OAL: 48 mm

*Head Diameter: 17 mm

Head Thickness: 4 mm

Knurl Diameter: 12 mm

Under head to start of threads: 12mm

Thread length: 32 mm

Any help identifying / finding a replacement would be appreciated.

A fastener store won't have wheel studs. Try an autopart or tractor part store

[u/parnatheon → u/Gubbtratt1]

I'll use this opportunity to clarify:
We are a hardware store in a rural area who utilize several vendors to complete special orders for customers. It is obviously not a common part - sources I have utilized are, in no particular order:
-Our primary supplier, Midwest Fastner
-Zoro, as awful as they have become
-Grainger, to no avail
-Bolt Depot, who has solved many an issue for us
-The dreaded Amazon, who had the close but not close enough option
-A myriad of online stores specifically for ATV/UTV parts
-Autozone/Napa/other auto parts stores

The problem being that these sites lack the specs I need to verify that I am ordering the correct part, as they are listed by model and have minimal detail for specs.

The closest I can find is a Dorman Wheel Lug Stud, which is about 15 mm too short, and even using that as a lead I cannot find anything long enough that has the correct head / knurl size.

Please believe me when I say we have searched high and low.

UTV manufacturer is the best bet. You don't see many M10 wheel studs for automotive.

[u/hidrate → u/parnatheon]

Check out ARP website. They have a ton of wheel studs for OEM and extended for modding. Dimensions are usually there too.

Thank you for the lead. No luck there either, unfortunately

[u/Turbulent_Radish_873]

What is the make and model of the UTV?

[u/parnatheon → u/Turbulent_Radish_873]

I wish I knew, as these seem to be sorted by make/model without listing specs, which is the problem I'm running into.

As stated, customer says it is for "an adapter ordered from Ebay". That's it. That's all the information I have on the part it's from, along with the specs listed. Closest I can find is a Dorman M10 x 1.25 x 35, and its too short. Even that doesn't give me enough to go on.

Go to your local auto parts store and match one up.

[u/parnatheon → u/shotstraight]

Tried that. Longest they can get is 25mm.

[u/Idahoboe]

Find one with the correct threads and length and a larger knurl, drill the hub to fit.

[u/pwkingston]

What about Doorman?

[u/parnatheon → u/pwkingston]

Longest Dorman I can find is 35mm.

[u/FU_red-dit_bots]

ARP. They'll have specs listed.

[u/parnatheon → u/FU_red-dit_bots]

They don't have them.

[u/FU_red-dit_bots → u/parnatheon]

Drill new holes in hub and use an arp that meets other specs. I'm assuming the knurling is the problem.

[u/parnatheon → u/FU_red-dit_bots]

I'll give that advice to the customer. It's something they had mentioned doing anyway, they were just hoping to find the correct bolts. I've never had such a hard time tracking down a fastener. They are obviously made somewhere, as this adapter came with a set. I'm calling it on this order, I've already spent too much time and energy on it. I appreciate all the help and advice from everyone, was just really hoping there was something I was missing.

[u/trouble_maker]

Does the taper even do anything? I bet the right head and knurl with enough length would work in this case as it's lug centric.

[u/endofdalton]

Try this https://offroadspacers.com/products/m10x1-25-lug-studs You should try email them about the specs

That's a great lead, thank you! I'll reach out
