Like everything else in this 'aftermarket' supply chain
for our LBC's I can only believe $$ price is why these
'studs' stretch so much. Plain and simple, they're crappy
far east recycled US car metal.
The only rhyme or reason that truly seems realistic is where
else are you going to find a threaded at both ends, bolt,
with the right thread pitch. So we're stuck buying them.
Let's face it, high carbon steel 4" fine thread bolts don't cost
what ARP's cost. (above mentioned 4"ers are $124.00 per 100ct.
in the catalogs with a tensile strength of 70,000 lbs.)
...just like 'lowered' springs. B$%^S$%$ These are the springs we all
need the most as they are the stock CB model springs.
Distributors call them 'lowered' and charge more for them.
My 'lowered' springs, put my car at the 'book spec' ride height.
lowered my A__ !

I agree with Lawrie.
There was one type of stud that usually had a little '22' on the top that was
absolute crap - it wouldn't take regular torque half the time, and would
break if you went one pound over (or sometimes under!).
The later ones, supplied as replacements for MGBs, usually had a little
dimple in the end (where they centred them for machining) and they were much
better, but still stretched a bit, and had a limited useful life - I would
replace them every two seasons on my race cars.
The best solution seems to be ARP studs that have, if not an unlimited
service life, at least a very long one. Probably overkill for street MGs.
I don't have the same problem in the car I run the Twincam in, as they use a
larger diameter stud, which I have specially machined.
