Question: 1 / 400

Is the statement true or false? A screw extractor features hardened steel fingers that engage with a broken bolt's threads.

True

False

The statement is false. A screw extractor is designed to remove broken bolts or screws, but it does not typically feature hardened steel fingers that engage with the broken bolt's threads. Instead, screw extractors are usually tapered tools with fluted ends that are specifically engineered to grip the inside walls of a drilled hole within the broken fastener. When inserted into a drilled hole, the extractor works by turning counterclockwise to latch onto the threads of the broken bolt, allowing it to be removed. The design and function of a screw extractor highlight its purpose as an extraction tool rather than one that engages with the external threads of a broken bolt.
