$50 US bounty for 6.3mm x 1.0tp bolts. Euro members?
This is bordering on obsurd!
Past 2.5 weeks have been spent trying to find bolts for the front rotors on these OZ wheels. They're tapped for 6.3mm x 1.00 tp instead of the stock 6mm x 1.00 tp
Nobody in the US has them, and I have been all over the internet. Appears to be a European thing?
Will pay $50 US, plus cost of bolts, plus cost of shipping for:
12 6.3mm x 1.00 tp grade 5 or better, preferably button head (stock rotor bolt appearance) bolts. Need to be around stock length of 17mm or so.
Anybody?

I can't believe it either!
Talked with the consultant from OZ and he is talking with them hopefully this week. He found a set of titanium bolts with OZ's logo he said he'd send over, but they are 7mm and I don't want to risk retapping these wheels.
I have a 6.3mm tap in my hands right now, so somebody has to make a bolt for that hole!
Getting cranky since I can't ride when the weather is good. Might go buy a 929 front wheel from a breaker yard to get me rolling until this is resolved.

Re: $50 US bounty for 6.3mm x 1.0tp bolts. Euro members?
Is it possible that this is a 1/4 x24 SAE bolt hole ?
If not where did you get a 6.3mm tap.
I've been around the motorcycle industry for about 35 years and have never heard of that particular thread size/dimension.
I also contacted several hardware supply houses after reading your post and was advised it does not exist.
Considering the fact that the OZ rep couldn't help you it seems that the previous owner of the wheels may have retapped the hole to 1/4 x24 or it is simply a worn 6x1mm bolt hole.
If this were April 1st I'd givve you credit for a really good one.

BTW does the above info qualify for the $50 bounty ?

Here I go with my fancy engineering numbers again:
6.3mm / 25.4 mm per inch = 0.248 <-- Pretty close to 1/4" bolt, especially if it's a loose 6.3mm
Why would manufacturers make a bolt with no matching socket? Thinking about it, I have a pretty complete socket set, and only a 6mm, 6.5mm and 7mm socket. I bet you are right Kai Ju.

Re: $50 US bounty for 6.3mm x 1.0tp bolts. Euro members?
Behold:
http://www.amazon.com/gp/product/B00...lance&n=228013
The one I have came from a friends craftsman tool set. Has a matching die as well.
The wheels are brand new from OZ, I'm still waiting to here the final word from them. That tap is definately what fits the hole though.
6.3mm is 1/4", but the thread pitch is definately 1.00 metric. The local hardware store had even heard of them, just hadn't seen them in a loooooooong time

Seeing as you have a tap & die set that covers this thread, why don't you makes some? Assuming OZ can't help you of course.
This way is you will have a custom bolt set that no-one else will have! Could look very trick if you used the right material.

LOL
Was going to try and get some 7's and convert them into 6.3's, but not sure if that'll work? Thought there was something special about the surface on the bolts I'd be removing if I did that?

I think I have good news. 6.3 is apparently the metric designation for a 1/4-20 thread.
You should check out this information and see if you come to the same inference as me:

GM used it in the US for body fasteners,, and apparently, OZ used it for their wheel sets.
Personally.. I'd be looking at enlarging the hole to a standard fastener size,, OR installing a 6mm stainless thread insert. Again for use of a standard fastener.

Also... As I posted above.. If it were me,,, I'd be drilling and installing a Helicoil 6mm thread insert. And be done with the silliness. If you were close I'd offer to do the work for ya.

Re: $50 US bounty for 6.3mm x 1.0tp bolts. Euro members?
Current fastener
6.3mm x 1.0.. Major diameter 6.3 mm
Helicoil 6mm x 1.0 SS thread insert. Available in 6, 9 or 12mm long
Drill size 1/4" (6.35mm)
So,, you drill out the 6.3mm hole to 6.35mm (1/4") insert a SS thread insert. and use a standard 6mm x 1.0 button head fastener available in most any hard ware store. Deal done. No concerns with finding/using an obsolete fastener.
The whole deal could be done in an hour or so with some experience. Or contact a local machine shop. Labor charge should be minimal.

LOL! Thanks for all the help!
OZ wrote back, and they don't seem to have any either?! They don't do the bike wheels any more, just cars. I'm dying to know why they went with such an oddball size.
The guy I got the wheels from is having them send a dozen 7mm x 1.00 TP, 10 point, titanium bolts (didn't know they made bolts out of that!) over, then we'll get the wheel rethreaded to take that size. More complicated then I'd like, but its not costing anything so...
They're sending over the tool to install them as well, since 10 point is kinda rare over here? Trading one odd-ball fastener for another it seems (but these even have the OZ logo on each one
).

Re: $50 US bounty for 6.3mm x 1.0tp bolts. Euro members?
Hate ta say this.. but your plan will not work.... a 7mm x 1.0 tap uses a 6mm drill size... your hole is already bigger than that,,,, at 6.3mm
The end result is,, when you run that 7mm x 1.0 tap though the hole,, your new threads will not be full depth. Not the best situation for a brake rotor fastener.
Ti is a common material for thread fasteners. Pricy,, but common.
A 7mm x 1.0 SS thread insert uses a Lettered drill.. "L" which is 7.4mm for the starting hole before you run the tap through. If your stuck on using the 7mm fasteners.... and the material on the hub is available,, that is the way I would go.. so the 7mm fastener has full thread depth.
..
NOTE I am not an engineer... so take what I've said with a grain of salt. It's what I've learned over 40 years of wrenching and fab work,, and what I believe to be right.... But school trained I am not.

Re: $50 US bounty for 6.3mm x 1.0tp bolts. Euro members?
See, there ya go. I did mention I only do this stuff,,, not that I knew the actual engineering data :P
I like to install SS thread inserts in most any aluminum part that sees repeated fastener installation and removal.
If the ME says it will work.. Go for it

This place has a number of 6.3 x 1.0 bolts.

They are just down the road from my house. If you find what you need let me know and I can get them for you. Might be a box of them though....

With pictures even!! Just called the number and it seems they're closed, I'll be trying them again tomorrow!
We may have a winner!! Was calling around to machine shops just a few minutes ago too!
Thanks!! You might be getting a paypal soon...

Also, they are a wholesaler so they are only open mon-fri 8-5 pm. That is the reason that you may end up with a box of 50 and they do not come cheap.
