The present disclosure relates to a tolerance compensation device for bridging a distance between two components to be connected to one another, comprising a base element and a compensating element which can be screwed into the base element, the base element forming at least one stop and the compensating element having at least one elastically deformable transport securing means which is designed in such a way that it must overcome the stop with temporary deformation in order to screw the compensating element into the base element.

A thermally stabilized fastener system and method is disclosed. The disclosed system/method integrates a fastener (FAS) incorporating a faster retention head (FRH), fastener retention body (FRB), and fastener retention tip (FRT) to couple a mechanical member stack (MMS) in a thermally stabilized fashion using a fastener retention receiver (FRR). The MMS includes a temperature compensating member (TCM), a first retention member (FRM), and an optional second retention member (SRM). The TCM is constructed using a tailored thermal expansion coefficient (TTC) that permits the TCM to compensate for the thermal expansion characteristics of the FAS, FRM, and SRM such that the force applied by the FRH and FRR portions of the FAS to the MMS is tailored to a specific temperature force profile (TFP) over changes in MMS/FAS temperature. The TCM may be selected with a TTC to achieve a uniform TFP over changes in MMS/FAS temperature.

A support component that supports a shielding member, and a fixing component that fixes the shielding member to the structure via the support component. The support component has a cylindrical part, two flange parts and spring part. The spring parts have a first spring and a second spring with different load-deflection characteristics. The first spring and the second spring are interposed between each of the two flange parts and both sides of the shielding member. As a result, the invention provides a sufficient buffering effect.
