Screw Extractors - purpose
and using instructions
A broken bolt or screw may be removed from a hole with
a Screw Extractor. First, Drill a hole in the broken bolt. The
correct Drill size to use is shown below and is also stamped
on each Screw Extractor. Insert Screw Extractor in the hole
and, with a Tap Wrench, turn counterclockwise. The Screw
Extractor acts like a corkscrew. It grips into the sides of
the Drilled hole and removes the broken part on its own
threads without damaging the threaded hole.
