To release a screw or bolt screwed into a corroded metal piece, we can adopt various techniques including:

unlock screw bolt
  • Unlocking oil , first of all we oil the locked screw with a special unlocking oil trying to let the oil penetrate.
  • If this is not enough, heat the piece with a torch so that the expansion of the metal removes the corrosion from the screw.
  • If the piece cannot heat up for various reasons, for example painting or plastic pieces nearby, it is still possible to use a impact screwdriver . Uncommon tool but very useful and effective in extreme cases, it is used by beating as on a chisel and it acts by rotating independently to unscrew.
