have just striped down the rear springs on my 2 door saloon so i can clean them and paint them and replace the perrished rubbers that the u-bolts go through. well to seperat the leafs you have to undo the center bolt and spacer that goes through the 5 leafs to locate them. you've guessed it, one side came off and the other went crack and bounced all over the garage

. sheared straight off flush with the bottom leaf

. well i've had a good look round and can't find any for sale. anybody know where i can get one. i do have access to a lathe and have some stock 22mm 303 stainless i guess that may be the way to go.
ideas more than welcome.

Charles Wares list them as pt No SUS 715 - dowel bolt.
youd probably be able to machine one yourself fairly easily.

You can probably just use an Cap Head Allen screw ?? Maybe grind off any excess head after installation - and likely to be much better spec steel too. Wouldn't use stainless next to steel - sets up a cell when wet - and the steel around the stainless dissolves......

charles ware list the part but not the price. makes me think that its discontinued, will have to call em.
i take it then that you should only use s/s fittings on s/s. and steel fittings on steel. puts a whole new slant on all those sparkling screws you find at auto jumbles then. i take the point though of some sort of a chemical reaction, not being a chemist i will have to bow to experiance. ta

Most stainless screws/bolts don't have the necessary tensile strength anyway for any 'serious' use. Cap screws are v high tensile - ideal for the job.

bmcecosse,
i think its call "GALVANIC CORROSION"
when 2 dissimillar metals are brought together an electrical state is brought about, because they have differant compositions they have differant electrical charastircs. i remember from my motor bike days trying to take off the engine covers. always stuck and the bolts were covered in corrosion. steel bolt alloy case = galvanic corrosion. easy in it

Exactly! Yet 'stainless' studs are sold (and bought) by many - who think it will solve their problems !
