Tolerance compensating device for rotating and tilting bolts

A closure comprising:

• a pull-turn bolt or swiveling bolt for mounting in thin walls, the bolt having a tolerance compensating device with a back-engaging device located at a free end of the bolt;
• said bolt having a bore hole near its free end in which the back-engaging device is held so as to be displaceable perpendicular to a back-engagement plane of a back-engagement surface of a frame;
• said back-engaging device having a spring which forces a contacting portion of the back-engaging device in a direction towards the back-engagement surface of the frame when the closure is in the closed position, so that the contacting portion of the back-engaging device contacts the back-engagement surface of the frame;
• said back-engaging device adapting to varying distances between the free end of the bolt and the back-engagement surface of a frame by expansion and compression of the spring during use, so as to maintain contact with the back-engagement surface of the frame without need for manual adjustment of the back-engaging device;
• and
• said closure having a housing which holds said pull-turn bolt so as to be axially displaceable and rotatable or said closure having a housing which supports said swiveling bolt.
