Hi ,know that in some cases that metric and imperial arent the same diameter size,but in some they very close.
chances of finding an imperial bolt in a long length is very rare,unc is better than unf though.
a fully threaded bolt is called a set screw.

I changed all my 5/16unf to m8 stainless steel on the steering joints.

anyway ,let me know

Oh my, what a lot of confusion i've caused :oops:

The part is 216901 as shown in the picture that Mart posted - NOT the long one that goes through the upper wishbone. To be honest, I was a little unsure what to call it, but the Haynes manual and Rimmers definately describe the dolomite as having double wishbone suspension - and in both Haynes and Rimmers terminology it is the bolt that connects the 'lower wishbone arm' (UKC1698) to the 'mounting bracket' (313290/1).

Thanks for the offer NO41Sprint, but i'd be happier knowing i've got the real thing (or nearest possible).

As I won't be able to get to Swansea Fasteners until Saturday, has anyone got an original going spare?

Thanks (and sorry for the confusion.)
Mark.

The length of these track control arm bolts is not particularly long, so these shouldn't be a problem to obtain.

It is worth replacing these bolts, particularly on a car that has been unused and left outside for a long period, as the bolts may have rusted inside the bush. This occurred on the Sprint I rebuilt in the 90s. On one side the rusting had considerably reduced the bolt's diameter!

Is it safe to use stainless steel bolts in a high load application such as the steering?

You are right Mark, the terminology is confusing, especially as different names can be used for the same component!

In the case of Dolomites, the lower wishbone consists of two components - the track control arm UKC1698(which takes the lower ball joint) and tie bar 218482(bolted to TCA and subframe).
And as you said Rimmers add to the confusion, as their catalogue describes UKC1698 as "lower wishbone arm" and 218482 as "drag strut".

Hope this makes it a little clearer. Having encountered this confusion with terminology I try to use the component part numbers if I have a parts list I can consult.

Now that I know which bolt Mark wants it is important to point out the non standard bolt head on this component which is machined slightly domed to prevent it causing damage to the steering rack gaitors!

Have been stripping my front suspension today so that I can re-bush it - but the damn pivot bolt that connects the lower wishbone to the mounting bracket was stuck fast so I had to cut it off.

Trouble is that Rimmers list this part as 'no longer available' (part 216901)
At least some of us take note of what the post said. :wink: :lol:

Hi
Stainless steel is just under grade 8.8 or in otherwords high tensile.

All unf and unc bolts are to the equivilant of 8.8.

Swansea fasteners buy from us................

cheers

Hi Mark

This is why I am sad and know anorak stuff as its my day job .

I pinched a £1.50 bolt from Swansea Fasteners the other day :twisted:


Well... I asked the price of such a size bolt,
"Yerp there £1.50 each"
*thinks to self, "oh I have £5, I will be able to afford 3 of them"
"I'll have 3 please"
Places a bag infront of me with 3 bolts in
"thatll be £5 odd"
:roll: WTF is the point of telling me the price with out VAT added to it when I have to pay VAT?! Why not just tell me the price thet're made for and then add whatever extras need to be added in to the price when I come to pay you!? Fu**ers!
Got an extra bolt when he forgot to take one back off me though....



So the morale of that short story is 'keep peoples minds occupied and you can rob them silly' :twisted:

Don't forget that with most suspension set ups you'll need high shear bolts, and most of your normal fixing companies don't stock anything that would suit it would have to be special order items.

Hi All,

I have been searching for 2 new Pivot bolt 216901 with no sucess, I see from the thread below that this has come up before.

does anyone know where I can get two? I have tried the usual suspects but reached a dead end.

If anyone knows the length of the shoulder and the length of the tread, (I know it is 3/8 UNF, I can ask my friendly fastner company to make a batch in high tensile material.

Thanks

Give Mick Dolphin a call, his website is showing stock at £2 each.

I wouldn't put stainless anywhere near my suspension or steering, it's too brittle and if you use your car in the winter then salt will cause chloride stress cracking and potentially failure. The tensile strength is not too different but the shear strength is quite different to regular steel bolts used in suspension.
