Special bolts

[Typhoon]

I'm looking for some M10 x 1.0 x 60mm grade 10.9 socket head bolts, none of the places I've been to or contacted online keep them in the thread pitch I need.
Anyone got a good source?

Specialty Fasteners can't help ??

that's a nasty size, you would have to have them custom made.

Nah doesnt need to be custom made, its an M10 fine bolt, I purchased some in the UK a few months back as I needed a couple.

Tried Specialty, they only had hex head in the size I need. They're Alfa CV joint flange bolts, need a small head for clearance.
It's the 1.0mm thread pitch that's the killer.

Source? I've bought stainlless bolts from the UK before, the Brits have always been good with engineering stuff.

it's M10 extra fine, M10 fine is 1.25mm. The fact that it needs to be a socket head is what makes it hard though (i have a very small range of 10x1.0 hex head bolts here, they certainly exist). I have had a quick look this morning, none of my suppliers do one in a socket head though.

Try WestTrac for CAT bolts as they are a large stockist of 12point fasteners

Yep 10 x 1.0 is a nigger size and you won't get them except second hand or possibly, new genuine.
When I played with Alfas I repaired the 8 x 1.0 shcs on CV drive flanges with 3/8 unf and the 10 x 1.0 with 7/16 unf shcs.

The CV joint bodies drill OK, only the races are hard, and the drive flanges tap easily enough; the std CV bolt hole is a good guide for the 10.00 mm tap drill size if you are doing them on the car.

yeah my bad, I skipped the part about socket head.

I found some.
After calling everywhere all over Australia and being told "too hard" and firing off emails all over the world, this guy helped me out:

He has a few left, so it could be a good idea to buy some for your stockpiles if you're a sad cunt and like Alfa transaxles.

M10f 1.00 x 60 is not listed by any normal supplier in Australia.

I have some 40 long but that isn't much use. I think you did well to track them down.

I was almost resigned to drilling oversize and going UNF as Momus suggested above. If I hadn't found them by new year I was going to do that.
The problem with these bloody bolts is the heads are usually partially flogged out by some brainiac that's had a go at them with plain Allen keys before, instead of spending $10 on a proper 1/2" drive socket.
Needless to say, I bought some spares.

It's amazing how hard some stuff is to get, particularly metric stuff. Even going to specialty bolt shops they look at you like you're an idiot.

[Nathan Tinkler]

If they used a commercially available size then things would be easier.

I think that using a one off bolt is to get you to pay through the nose for oem..

[lysdexia]

True that. If I had a dollar for the number of people that i flat out can not help on a daily basis, i'd be a rich man.

I think it was probably more along the lines of "O.K, now, how do we attach a CV joint to this bloody transaxle?!?!? If they'd used a UV joint it would've meant shorter bolts, even if they'd used a 1.25 pitch thread it would have been no issue, but I bet some engineer said something about extra clamping power and strength and specified the 1.0mm thread pitch.
Hell, today we'd just have a splined CV joint stub and the joint would just drop into teh side of the differential and be held with a c clip.....
Who knows, maybe 1.0mm pitch was more readily available, 25 years ago? I don't quite think the Italians had the concept of built in dealer dependence back then, they did well enough with manufacturing defects!
