Sheffield Alpha HSS Screw Extractor Gauge Cobalt Series Carded

$6.35 inc.GST
SKU SHE9SE01
  • Reverse Tapered Cutting Screw Thread
  • Square Head for use with Tapping Handles
  • 5 Common sizes available

Directions for use:

  • If possible, grind or flatten the head of the damaged bolt or screw.
  • With a heavy hammer and centre punch, mark the centre of the bolt or screw; this will prevent the pilot drill wandering.
  • The extractor requires a pilot hole, start with a small Alpha left handed drill bit (e.g. 5/64??????).
  • If required, drill the hole out larger. It is best to use a left-hand drill for this step, as this may be enough to remove the stud without a screw extractor.
  • Select the correct size screw extractor for the hole, see table above.
  • With a tap wrench, turn the screw extractor into the hole in an anti-clockwise direction. The reverse threads force the extractor into the hole until the broken bolt or stud is forced to turn. Continue turning until the stud is removed.
