Hi
Does anyone know if new head studs, head nuts, and manifold nuts have been manufactured and by whom or who can I contact about these
Regards
Ian

Manifold studs can be made from cut-down metric 8mm x 1mm bolts (aka Metric Fine thread 8mm), if you can find this 'oddball' size.

Hi Rob
I dont need manifold studs but manifold nuts and i did use unf nuts welded together to get the length of nuts before so i assumed mine were unf thread
Ian

Head studs are M10 fine, Manifold studs are M8 fine. Head studs are 3 different lengths. When I needed to replace a head stud on an old engine I used a bolt of the correct thread and length. I had to buy a 17mm socket to fit the head.
Have you got a local engineering shop that can cut a thread through a length of hex bar for the nuts, if so is the cost acceptable?
Have you tried club spares or Carlo?

Hi Mike
I asked a guy I know to price some long brass manifold nuts and he said it would cost 75 Euro ( 62 Pounds) said he would have to machine up the hex from larger bar I dont think he was that interested also asked him prices to make up plates to match exhaust gasket want to play at making twin carb setup and tubular exhaust he said he would bore holes and cut square holes but I would have to shape them myself and cost was high for that too
Ian.

My manifold nuts are not brass on any of my 3 engines. If you can find a friendly machine shop it should be possible to continuously cut a thread throgh a hex bar then cut it to length. You would then have double ended manifold nuts, the standard nuts are only threaded at one end. It would put the cost up if you insist on 1/4 Whit hex size.

I made my own. Brass 15 or 17mm hex bar is about £10 for 2 feet. There appear to be 2 types of manifold nut and a variety of thread patterns in use. I have taps for all of the options so can knock up some for anyone who gets stuck.

We are using Unbrako cap screws for head bolts, about 9 quid in Australia for the complete set

Hi
Any website address for these capscrews and what do they look like
Regards Ian
Edit Found the website for these capscrews

My rebuilt engine had a new set of head studs made for it as well as a set of manifold studs and brass nuts, hex size to fit 5/16 whit spanner. The hex had to be ground off the manifold end of the nuts as they were too large, the engine builder did not have the manifold to work with

Probably worth remembering that any engine bolt that requires torquing up, from grade 5 upwards, must have the threads pressed/rolled into it, you cannot cut them with a die, they are weakened by this process

Its a bit of a cheek for us to raid them but the Morris Register had those metric nuts and studs and kindly sold me some.

I got fabulous service from one of those Morris 8 suppliers ;-) contact details should be available via Mike or PM me for details.
Ideal source for many sidevalve parts IMHO - although the engines have some differences.
Morris Register spares wasn't functioning when I needed the parts but the previous guys were still pleasant enough.

I had a set of new head studs and nuts last year for a sidevalve rebuild. The head bolt lengths were not perfect as the heads are not identical (3 different lengths short was ok, mid length was longer and would also fit long studs, long studs were very long). Shortening the studs was easy compared to having some made up!
