M12 stud bar ?

What do ya need it for? If to hold diff in place i used 2 lengths of M12 threaded bar.

Will do it.

But to be honest I used two shorter bolts to mount it rather than one massive one.

HTH,

I bought the proper ones from ford. Not a huge amount of money - not nasty threaded bar.

Its for part of my rear upright setup, not for the diff, just heard that the one used on the diff is long, hopefully long enough for my application - just don't know how long it is. I could use threaded bar, but have little clearance to the wheel, and would have problem tightening it, without 'pulling' too much of the threaded bar trough the nut. So really could do with a bolt.

Mark,

Why's threaded bar nasty ? Did you have a bad experience as a child

I may have a spare set of bolts at home, will have to check tonight though.

Ah, ok. You did say diff in your first post!

I bought the long bolts for the uprights from AHC aswell.

Cheers,
James

EDIT: Just re-read you posts again....if you've got MK rear uprights then no, the Sierra diff bolts aren't long enough for them.

I have several diff bolts picked up from floor of Scrappy and not long enough.

Aha!

I have had this very type of problem in the past with front inner wishbone bolts.

Normal threaded bar is a no-no as it is usually pretty much just mild steel.

What you want is a length of 12mm diameter EN24T bright steel bar (or 817M40 high tensile bright bar in Europe)

just cut it to length and thread it in the right places, then use a pair of 1/2 nuts at one end and a nyloc at the other.....job done.

EN24T is around 900N/sq mm tensile which is stronger than 8.8 class bolts. (these being around 880 surprisingly enough!)

Bolts usually fit in a hole to locate something. if the load is bearing on threads rather than a plain shaft then there is 'IMHO' more chance of the thing either wearing the threaded bit or the threads wearing the compnent out.

It seems more like a bodge than a proper job to me.

And it's sharp on my hands when I pick it up

I don't think you'll have any ill effects by clamping the diff with M12, which was what I thought the original question was.

But to accuse me of being a bodger, you b*stard !

Are you going to Donny, I'll bring the pistols

Each to his own, but if was coming to Donny I would insist on using my own water pistol

Hi Rayroni

Haven't used these yet but might be worth checking out, they seem to do some weird and wonderful sizes!

You can get high tensile studding, also the longer nuts to go with it.

I got my diff bolts from Namrick - they didn't seem fazed by the length and delivered next day. They may have longer ones for your wishbones
