Abstract: The bolt lock with protective cover has a back enclosure containing a sliding bolt which combination is inserted into a cover enclosure. The cover enclosure with back enclosure is attached to a door, gate or other such structure for purposes of securing the closure. The sliding bolt is slidably engaged with an insertion end, a bolt end and an intermediate element to guide and retain the bolt for slidable engagement with a shackle and retention of a padlock. The slide bolt has orthogonal locking pins and a handle to move the slide bolt into a locked and unlocked position and to retain the bolt when the padlock is locked. A bolt lock end passes through a hole in the back enclosure bolt end and an exit hole in the cover enclosure bolt end to engage a structure such as door jamb.
