Final answer:
Screw extractors are devices used to remove broken screws, studs, or bolts in threaded holes. They have a reverse-threaded bit or a tapered flute design to grip and extract the broken fastener. Intermediate taps, pullers, and tap handles are not designed for this purpose.
Step-by-step explanation:
Screw extractors are devices designed to remove screws, studs, or bolts that have broken off in threaded holes. They typically have a reverse-threaded bit or a tapered flute design that grips onto the broken fastener and allows it to be twisted out.
One example of a screw extractor is an EZ-Out, which consists of a small drill bit used to create a pilot hole in the broken fastener, followed by a screw extractor bit that is inserted into the pilot hole and used to extract the broken fastener. Screw extractors can be used with a tap handle to provide leverage and better control during the extraction process.
Intermediate taps, pullers, and tap handles are not specifically designed for the removal of broken screws, studs, or bolts in threaded holes.
