A tamperproof, secure mounting system for a deadbolt lock is adapted to accommodate a wide range of door thicknesses. The device includes a front section and a rear section which are passed through the front and rear ends of a hole formed through the door. The portions of the front and rear sections which meet within the door hole are threaded together to clamp the door between the front and rear sections. Supplemental fastening means are provided to secure the front and rear sections together to prevent further relative rotation between the two. The front section carries the tumbler mechanism so that thekey slot of the tumbler mechanism is exposed at the front of the door. The rear section is hollow and provides a passageway by which the rear end of the tumbler mechanism may be connected to the lock which mounts on the inner face of the door. Means are provided for registering the rearwardly facing surface of the rear section with the lock.
