ABSTRACT:
A two-part threaded locking mechanism is provided with complementary stop elements in the form of a pin and a recess that interengage when the two lock elements are threaded together. When used as a padlock, the locking mechanism may be encased in a tapered, spinnable, protective shroud. To facilitate assembly, the recess may be made larger than the pin and the surface adjacent the recess facing the pin may be spirally ramped.
