Stop screw

Abstract

Stop screw (100) with a screw body (102), with a thread (104) formed at least partially on the outer circumference of the screw body (102), with a central recess (108) extending along a longitudinal axis (106) of the screw body (102) within the screw body (102), with at least one detent ball (110) adjustable radially with respect to the longitudinal axis (106), wherein the at least one detent ball (110) is arranged in a spherical opening (112) formed radially with respect to the longitudinal axis (106) in the screw body (102), wherein the spherical opening (112) has a diameter that is smaller than the diameter of the spherical opening of the at least one detent ball (110), with a plunger (114) arranged in the central recess (108) and mounted to be axially displaceable along the longitudinal axis (106), which has a cone oriented axially along the longitudinal axis (106). (116) includes, which is established,to act upon the at least one detent ball (110) radially with a force, wherein a receiving section (118) on the plunger (114) adjoins the cone (116) for receiving the at least one detent ball (110), with a spring (120) arranged in the central recess (108) and aligned along the longitudinal axis (106), which axially acts upon the plunger (114) with a spring force, and with a stop area (122) present at a free end of the screw body (102), which provides a stop surface (124), characterized in that the stop surface (124) is curved with a radius.
