  • Patent number: 6357953
    Abstract: A tolerance compensator provides a predetermined tolerance or space between connected assembly members. The tolerance compensator has a pair of connector components a first of which is secured to one of the assembly members and the second connector component is threadably installed, with a left hand thread, into the first connector component. A threaded fastener, with a right hand thread, is inserted into the connector components to initially engage the second connector component, either threadably or frictionally, to cause relative rotation between the first and second components whereby the second component advances toward and engages the second assembly member. The threaded fastener also threadably engages the first connector component to provide a secure connection between assembly members with the designed tolerance or space therebetween.
