ABSTRACT:
A door set has its door knob engageable with a bolt pin through an eye which is formed in one piece with a screw threaded into a shank of the bolt pin to enable axial adjustment of the effective length of the bolt. The relative rotation of the shank and of the screw can be effected from within or even by rotation of the bolt, for which purpose flats can be provided on the bolt and on a sleeve in which the bolt is guided. The threaded portion of the screw can be provided on ribs which can pass axially along grooves in the internal thread on the shank of the bolt.
