How do I remove 7mm snapped off stud ?

[Blue.]

I always weld a washer on them then weld a bolt to the washer,never missed yet.

They are called cap screws and readily available from most nut and bolt places. Your local sparex dealer will be able to order them.

The "Ground Shoulder Screw"/ "Socket shoulder screw", are not quite the same as the basic cap screw.

Many thanks. I think that is the least of my problems compared with getting the snapped of screw out!!!

Looks nice n new, soak wd40 left hand drill bit, if its your day it will come out.

Forget WD40, it's not a penetrant/release lubricant, be just as effective peeing on it.
Plusgas is the stuff you want. Very effective and only need tiny amounts.

Or you can break out the acetone and atf, works wonders!

add some heat and candle wax will be loose afterwards

Many thanks everyone,I got freelance engineer I know ,to do it for me . I did not want to start the job get in a mess then asksome one to fix it. Just as well I did as Phil had quite a job on,fortunately he had some gas with him to heat stud up as he reckoned it was Loctited.I managed to get a new "Shoulder screw" in Cheltenham so all is well.

I would weld a small nut to it (one that sits inside the hole) then weld a bigger nut too it. Warming it up by welding it twice should loosen the threads

So to put all our minds at rest .....
Which method did he use?

Why don't you simply grind off the old nut and weld a new nut on in its place , done

I think he drilled , toryx, plus heat , not as easy as that though!!!
I just let Phil get on with it, nothing worse than someone looking over ones shoulder and chattering.

Except looking over your shoulder and "helping"

colbalt drills, snap on easy outs and plenty of heat, just dont snap the easy out off in the hole or your day will just get ten times worse!!!!!!

Did plenty of 10mm bolts yesterday, forgot to take photos but same procedure as @MF-ANDY. The heat from welding makes a difference. Had a few that had snapped way down but managed to build them up with the welder

Seems to be lots of these since the impact gun became popular.

I find that if the stud is quenched straight after the welding, it comes out even easier.

No need for a mag drill. They were nearly flush so welding was easy
