Just find a bolt of the same diameter & thread pitch (1/4"-20) and cut it down to length. If you want the 'real thing' I'm sure that the manufacturer of your tripod will sell you spares at an extortionate price. Failing that, you can get them from a certain auction site for a quid or so!

Would it be possible to very carefully superglue the end of a new bolt onto the broken face of the old one stuck in the scope foot and extract it that way? Risky I know ...

Modern tripods and accessories are 1/4 inch whitworth. Old Russian equipment used 3/8th whitworth
Tripod threads are universally Whitworth. UNC is close but is not the same.

Hi,
Wikipedia and as it seems, ISO beg to disagree... 1/4-20 UNC or 3/8-16 UNC...
en.wikipedia.org
But I have to admit that I didn't spend 38€ for the privilege to actually check the ISO text...

They are different but whether it matters I don't know.
Larger cameras use 3/8 inch.
Although Russian equipment often use 3/8 inch the Russian tolerances are wide and can cause damage.
I put a brand new Zunow 50mm f/1.1 lens on a Kiev and damaged the chrome or zinc finish.
I only used one roll of film.
The Nikon, old Contax and Kiev lens mounts may seem to be the same, but they are all different.
The Exakta and Topcon lens mounts are also different.
The Minolta bayonet and Chinese copies are also different.
Similarly there is no standard 1.25 inch eyepiece size.
They all differ.
This can matter as eyepieces can fall out or jam.
Some people confuse the Pentax/Practika lens mount with a T2 mount. These are totally different and cause damage.
Independent adapters also vary and can cause damage.
Kilfitt, Zoomar and similar are more expensive as they are made to stricter standards.
SRB Griturn have a large range of adapters and make specials.

B.

Wrong bolt size can be damaging.
The extreme example is with the 1990 incident with a BAC 111 where the captain was sucked out of the aircraft but amazingly survived.
Some of the window bolts were 2.5mm too short or 0.66mm too small.
Others were the correct size.
The reference suggests that in this case UNC and British standards are the same.
My PST hydrogen alpha scope is mounted with a Slik tripod stud.
I like this system a lot, but the stud unscrews itself in use.
At nearly every use I check that the stud is firmly attached to the scope and properly locked onto the tripod head.
Generally I check that tripod studs are firm as they can easily become disattached even with a locking arrangement.
I would think that in long term use a UNC bolt in a Whitworth fitting and vice versa would cause wear.
