The present invention relats to a security door system for a hinged door and the like. More specifically, this security door system consists of a door, a door frame with a jamb aligned substantially parallel to the door, a plurality of hinges and a security bolt device. The security bolt device consists of two plates positioned on opposing sides of the door and along the hinged edge of the door. A security bolt protrusion positioned on the top side of the interior plate of the security bolt device is inserted into corresponding apertures along the door jamb. When the door is closed, the bolts along the hinged edge are positioned within the apertures to preclude removal of the door by merely removing hinge pins from the door hinges.
