Screwfinder™ is a magnetic hand tool, which helps you to take down wall boards in one piece with a minimal of effort and cleaning. It locates the hidden screws and thus the studs, beams and girders covered by the wallboards, wallpaper, paint or plaster.
Finds screws in walls!
Screwfinder finds hidden screws along with joists in plaster walls, chipboard walls, MDF boards, in principle in all types of construction boards. This allows boards to be dismounted whole. They can then be reused.
