A SUBSTITUTE PIN

Carton steel doors or bars on the Windows to the concrete or brick walls specialists usually fastened with sharp pins. If you need to remove the box, the case is difficult to pull the pins very difficult, and drown them interfere with the flattened outer ends. For these purposes I used the M10 screws, drilled them for the holes in the jamb with a diameter of 9.5 mm. If needed, you can screws to rotate, loosening their grip with the wall, and pull out tools at hand.
