Stripping out or breaking off a screw head is frustrating. Without the head to turn the screw, an extractor is required to do the work. Screw extractor kits are simple to use and save you time and money when making repairs that involve a stubborn screw. Kits come in different sizes, depending on the size of the screw being removed.

Drill a hole 1/16 to 1/8 inch deep in the centre of the top of the screw using a drill bit that is half or less the diameter of the screw.
Place the tapered extractor bit with spiral edges into the drill, and set the drill to turn counter clockwise. The extractor bit tip should be slightly smaller than the diameter of the hole drilled and should not reach the bottom of the hole.
Insert the tip of the extractor bit into the hole drilled in the top centre of the screw.
Hold firm pressure on the drill toward the screw while pumping the drill trigger in slow two-second bursts to back the screw out and remove it.
