OK Fred
I read your post and Ill see what I can do to help
Honestly your use of Smilies is distracting
A Single hexagon head bolt. Is called a “6 point”
The double hex or 12 pointer bolt is called 12 point
Allen head Bolts are still allen head
And Torx head bolts are still called Torx head
“A ring spanner fits perfect so I cut of the 14mm head and welded it to an old socket. I put it on a head bolt and a 1/2 inch driver and I could not shift it and I am a big bloke. So I got a tube on the driver and just sheared the socket 12 pointer to bits.”
“I need a black air drive socket that is hardened (Impact sockets_ but then it wont fit in the recess and you cant buy those in double hex.”
Correct Impact sockets have a thicker wall and wont fit in tight places So you are stuck with having to use a 12 point socket
I would recommend a top quality Socket Like Snap On, Matco or Mac These have the thinnest walls and are by far the strongest on the market.
Mazda B2800 4 valve diesel. I cant even get the head off my car
Ok You have a stuck bolt
The possible problems
Could be that it goes into a water jacket and his a bit of rust on the thread
Carbon could have passed by the gasket and contaminated the thread'
Or your socket is not strong enough to break the bolt free
I use many many ways of cracking bolts loose
One way is to tighten the bolt that is stuck and sometimes it frees up
I also Sock the bolt in transmission fluid because it wiks better then most oils and the detergent brakes down carbon and turns it into goo
First Smack the head of the bolt with a center punch and hammer Then if you can get it hot and poor some penetrating oil, I like PB blaster, or trans fluid on the bolt and let it sit for a couple hours or if you have time overnight is best.
When you get back to it Heat it up again a little more PB Tighten and crack it loose with a strong socket and breaker bar.
The firm strike with the hammer and punch and penetrating oil used together is the trick
If heating the bolt is not practical then heat the oil and poor it on the bolt
Heat thins the oil and allows it to penetrate deeper or wik
If the bolt is in a water jacket and the threads have rust on them tightening the bolt first helps to break the bolt free of contamination and you’re less likely to pull the rust through the bolthole
Know lets have a peak at this post

You said you were a diesel specialist in a head shop --- But you cant help with head bolts. I think you clean out kennels with Desirer.
Thats twice now a technical conversation sends you into cold shivers and childish rhetoric like bla bla.
Whats that!! what are you trying to say,-- bla bla black sheep have you any wool..
You know what Screw you
How about
Considering the quality of tools You English use you should probably purchase some good strong American tools. I have seen a set of Henrys and based on what I have seen British tools are crap. How they ever built a motorcycle as cool as the Vincent Black Shadow is a mystery More then Likely they copied a Japanese design or stole the design form Harley
And what idiot decided to use aircraft brakes on an automobile Oh Ya Rolls Royce
So yo must steal tires for a living
