ABSTRACT:
A motor-vehicle door lock has a lock bolt defining an axis and normally secured to the doorpost. A locking fork normally secured to the door edge can engage this lock bolt to retain the door against the doorpost. The bolt is formed of a rigid axially extending metal core and at least one axially deformable synthetic-resin body on the core. The core has a plurality of annular ridges having outer surfaces and defining a plurality of outwardly open annular grooves and the body fills these grooves and projects radially therefrom beyond the outer surface of the ridges. The ridges and grooves may be separate and annular, or may be the turns of a helical screwthread formation.
