| |  How to fix broke stud/bolt
If you are lucky enough to have broken a stud or bolt with threads left; you can use vise grip's, needle nose or pliers to remove stud/bolt. Thier are stud removal tool but most likely you won't have room to use....and it is a small eninvestment, if you brake alot of stud's and bolt's you may want to look into it.

If you have enough stud or threads left, you can make a slot and use a screwdriver to remove....I'm using a grinder but I have also used a hacksaw 
Make slot with grinder 
Slot on stud/bolt 
Now you can use screwdriver  |

Screw Extractor's 
Tool's you will need...Drill, drill bit, center punch, hammer, cresent wrench or right sized wrench, screw extractor..

Use center punch on center of stud/bolt for drilling...make's drilling much easier and helps keep drill hole in center 
Next..you want to start to drill...sometimes drilling with smaller drill bit, then bigger drill bit makes it easier. Always use nice sharp drill bit's or it will take forever.. Do your best to keep the hole centered... It's good to drill hole all they way threw, but sometimes not necessary 
Once you have your hole you can use the screw extractor 
Now you want to turn with wrench screw extractor counter clockwise  |

With any luck it will work great  
Now...If you break screw extractor in the bolt/stud you are in deep crap..Sometimes... The smaller the stud/bolt, the more difficult it will be..after a certain size, I will not use the screw extractor method
More to come when time is available.... |
