Broken bolts
by 1986chevyman on Jul 19 2018, 7:41 PMElite Tech
The best method I have found to remove a broken bolt or stud is to use a MIG welder. First unhook the battery( if broken bolt is on a vehicle). Next place the welder ground close to the broken bolt. Next, with the MIG welder heat turned up, start dab small welds on the broken bolt, as the weld begins to build up, hold the arc a little longer each time and eventually the bolt will be glowing red hot. Now you may attempt to remove the bolt with some vise grip pliers or other tool. By this point most broken bolts will come out. Sometimes, on a stubborn bolt, you may have to repeat this process 2 or 3 times.
What methods do you use to remove a broken bolt or stud?
