What Is a Screw Extractor?
A screw extractor is a tool designed with a reverse-threaded shape, specifically for removing broken bolts or stripped screws.
This tool works by threading its reverse thread into a hole, enabling the extraction of the target bolt or screw. Screw extractors come in two main types: individual and set type. The individual type is standalone, whereas the set type includes a screw extractor as part of a toolkit. Proper usage involves drilling a pilot hole with precision, threading the reverse thread cautiously, and applying the right amount of force to rotate and extract the target.
Key considerations during use include accurately centering the pilot hole and rotating the extractor slowly to avoid applying excessive force. The screw extractor plays a vital role in resolving issues with bolts or screws.
