BORDO Square Screw Extractor Set

  • Square Screw Extractor 5 Piece Set Nos 1-5
  • Chrome Molybdenum square screw extractor.
  • Square screw extractors feature four sided sharp undercut edges to provide a solid grip and will not expand damaged fastener during extraction.
  • They are ideally suited for removing broken bolts, studs & socket screws from medium to hard metals.
  • Typically the required screw extractor will be approx. 2/3 the diameter of the fixing you are extracting.
  • Use a centre punch to mark the centre of the fixing before drilling to prevent the drill bit wandering.
  • Select a drill bit that is suitable for drilling into the specific material – typically HSS or HSS-Co5. Ideally the drill should be “Left Hand” which will prevent further tightening of the fixing during drilling.
  • When using left hand drills ENSURE THE DRILL IS SET TO REVERSE.
  • Drill pilot hole in centre of broken bolt, screw or stud.
  • Lightly tap screw extractor into hole and turn anti-clockwise with a tap wrench or spanner.
  • Damaged bolt, screw or stud will unwind out of the hole.
  • Avoid excessive lateral loads – breakage could result.
  • Wear eye and hearing protection.
