How to use the tool:

  • 1. Position roller-type stud extractor on stud
  • 2. START turning stud extractor COUNTER CLOCK wise
  • 3. When stud removed, simply pull down stud extractor


  • Do not use roller-type stud extractor for tightening!
  • Studs are screws without a surface that can be gripped, which prevents their removal without damaging them. This tool is intended to do exactly that – removing studs without damaging the threads. The tool works through a system of three rollers that grip the stud at three points during removal, removing the stud without damaging it. The three rollers have no sharp edges, enabling removal without causing damage as they. Despite this, the tool can work in both directions. Tightening with the tool is not recommended though as the increased force in tightening could damage the system of rollers, which are dimensioned solely for loosening.
