Abstract
A door lock for locking a door to an underlying structure. A machine element disposed in connection to a through opening in the underlying structure is arranged so as to engage a bolt that is insertable into a through opening in the door. The machine element is inserted through the opening in the underlying structure to a position at which the openings in the door and the underlying structure form, together with the part of the machine element that extends outside of the underlying structure, a length that is longer than the bolt length, while at the same time an internal thread on the machine element extends sufficiently far through the underlying structure that, with the joint mounted, it engages the bolt to create the joint. Also, a method for manufacturing the door lock.
