The screw is drilled out with the appropriate drill and drill bushing. The extractor is then hammered into the hole with a brass hammer, because a steel hammer is more likely to cause the extractor to break. The appropriate special nut is then attached to the end of the extractor. The nuts can then be turned with a wrench to remove the screw. [1]
A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt. [2] The most prevalent form is the ratcheting socket wrench, often informally called a ratchet.
The inner nut is tightened to about a quarter to a half of the torque of the outer nut. It is then held in place by a wrench while the outer nut is tightened on top using the full torque. This arrangement causes the two nuts to push against each other, creating a tensile stress in the short section of the bolt that lies between them. Even when ...
A nutdriver or nut driver is a hand tool for tightening or loosening nuts and bolts. It essentially consists of a socket attached to a shaft and cylindrical handle and is similar in appearance and use to a screwdriver. [1] They generally have a hollow shaft to accommodate a shank onto which a nut is threaded.

Impact wrench – An air powered socket wrench that delivers high torque output by storing energy in a rotating mass, then delivering it suddenly to the output shaft. Nearly every auto body or mechanic shop will have an air compressor and impact wrench to loosen and tighten lug nuts on wheels.
