Abstract: The present disclosure relates to a screw connection comprising a support component, an additional component and a screw to affix the support component to the additional component. The support component comprises a tube made of plastic to accommodate the screw in a friction and positive fit, wherein the tube comprises a thermoplastic foam. The screw comprises a blunt-edged screw thread. The foam is compacted as the screw is driven into the tube. The present disclosure further relates to a corresponding screw and to a method of connecting a support component to an additional component using the screw.

Abstract: The present disclosure relates to a screw connection comprising a support component, an additional component and a screw to fasten the support component to the additional component. The support component has a tube made of thermoplastic foam to accommodate the screw in a friction and positive fit. The screw has a blunt-edged thread, enabling the screw to compress the foam in the tube as it is driven in. The ratio of the inner diameter of the tube to the diameter of the screw depends on the degree of foaming of the tube and decreases as the degree of foaming increases. In comparison to conventional screws, the threads of the screw of the present disclosure penetrate less deeply into the foam or they displace it, preventing damage to the tube while enabling a tight fit.
