Hex head drive flange bolts
I've searched, as I know the info is here but I can't find Rolling Eyes Big Cry

Want to replace the bolts when I have my new HD flanges fitted, but I can't find the full spec.

Seems to me they need to be 10.9 M10 45mm threaded just half way.

Anything else I need to know Question

Had hoped to find on eBay, but not been successful so far, any help appreciated Bow down Rob

Use hex socket head capscrews (what people incorrectly and annoyingly call "Allen bolts"), which are the right grade by default and widely available.

I used as Blackwolf recommended, they did the job perfectly.
IIRC 10.9 or 12.9 are sufficient tensile strength but no lower.

I have just checked the sizes you quoted against my old ones I took out I had them to hand luckily enough.
The sizes you mentioned are indeed correct.

Oh and don’t use SS bolts. But in my case I did not use Loctite at all on the threads and instead used stainless spring washers.
Then torque to correct torque. ____\We|Will|Win/___

just for the record.
10.9 grade standard . its bolts you want not setscrews (fully threaded)
socket cap screws (allan bolts) are 12.9 grade as standard

hope this helps 110 xs s/wagon

As a matter of passing engineering interest, this is the difference between a bolt and a setscrew - a bolt has a blind (unthreaded) portion, a setscrew is threaded thoughout its whole length.

Just thought you'd like to know.

Thanks very much guys, fascinating - but is there any chance of a link because I still can't find Rolling Eyes

If not, then no worries I'll make a trip to my local stockist called, believe it or not, Balls Grinding Snigger

When I did mine, I used galvanised socket head capscrews and matching spring washers, torqued to 65Nm:

I have the fronts to do shortly, when I've finished painting a set of HD drive flanges and my new wheels and tyres are ready:
