Broken screws are incredibly frustrating to remove, especially when it's just the screw head that's broken off. Fortunately, screw extractors make this process as clean and simple as possible. A screw extractor kit should include a number of different bits. Start with one of the two smallest bits to make a pilot hole, then tap an extractor bit into the pilot hole with a hammer until it's firmly in place. Using a pair of pliers, continue pushing down on the extractor bit but begin to turn it counter-clockwise. The broken screw should, with a little effort, begin to slide out.

Search for "stud extractor". Looks like a drill bit but the cutters are left hand thread, designed to be used with the drill in reverse. The lid of the box or the extractor should be marked to indicate a) the screw size they are designed to extract b) the drill bit size you use to drill a hole for the extractor. Before you start apply some penetrating oil. 1) Select the correct extractor for the bolt size. 2) Use a punch to make a dimple in the centre of the snapped shaft. 3) Drill a pilot hole a few mm deep with a drill. 4) Put the drill in reverse with the extractor in it. 5) Put the extractor in the hole and go for it. 6) If that doesn't work buy "freeze and release" spray and use as instructed then repeat 5).

a good way to remove a metal bolt is to get a screw extractor. You drill a small pilot hole down the middle of the bolt, and lightly tap the extractor into the hole. The bolt will then twist out. You may need to add lube to the bolt if its rusted (WD-40 etc.)
