- At least part of the adhesive tape is in direct contact with at least part of the pin-like connecting element and / or the counterpart.
- "Immediately in contact” means that the double-sided adhesive tape and the connecting element or the counterpart immediately, ie without another intervening layer of another material, adjacent to each other.
- At least part of the adhesive tape is in direct contact with at least part of the shaft and the head of the pin-like connecting element or with at least part of the shaft of the pin-like connecting element and at least part of the counterpart.
- the adhesive tape is preferably arranged at least partially in the gap between one of the components to be connected and the head of the pin-like connecting element or in the gap between the other component and the counterpart; In particular, the adhesive tape substantially completely fills the respective gap.
- “Completely filling in” means that application-related inclusion of bubbles in the bond interface or application-related inclusions of other materials are negligible in terms of application of negligible amount.
- the adhesive tape in the relevant section of the shaft surrounds it completely and immediately adjacent to it.
- a "double-sided adhesive tape” is understood as meaning an adhesive tape provided on both sides with a pressure-sensitive adhesive as outer layer, in which case it can be natural rubber, synthetic rubber or poly (meth) acrylate-based or have a different base;
- the weight-related main constituent of the PSA ie the constituent with the highest proportion by weight, is poly (meth) acrylate.
- poly (meth) acrylate here describes a polymer, its underlying monomers to a substantial proportion, preferably more than 50%, of acrylic acid, methacrylic acid, acrylic acid esters and / or methacrylic acid esters are formed.
- acrylic acid esters and / or methacrylic acid esters are compulsory constituents of the monomer base of the poly (meth) acrylate.
- the adhesive tape preferably contains a foamed layer.
- This foamed layer may itself be a pressure-sensitive adhesive and thus already form the double-sided adhesive tape.
- the foamed layer can, however, also act as a carrier material, a so-called "backing", and each have a layer of a pressure-sensitive adhesive on its top and bottom
- the foamed layer can be, for example, polyurethane, polyethylene or poly (meth) acrylate-based
- the foamed layer is poly (meth) acrylate-based within the meaning of the preceding paragraph:
- the main component by weight of the foamed layer is poly (meth) acrylate.
- Poly (meth) acrylate as the main component of both the foamed layer and the PSAs has been found to be particularly advantageous in terms of longevity, weatherability and strength. In the foamed layer, it also gives excellent shear strength and very good compressibility.
- the thickness of the double-sided adhesive tape is preferably 0.1 mm to 5 mm. This thickness range has proven to be particularly suitable, on the one hand to optimally fill the distance between the component and the head or counterpart of the connecting element and thereby compensate for unevenness in the surfaces of these components and on the other hand to ensure high bond strengths. In addition, results in this thickness range only a small deformation in torsions or displacements between the components and the connecting element or the counterpart.
- the mother can be fixed with the adhesive tape on a provided with a hole for the screw component, and the screw can then be tightened with a certain torque without additional fixation become. The application is also conceivable vice versa; Accordingly, the screw would be fixed and raised the mother.
- the adhesive tape can be attached first to the screw and / or to the nut as well as first to the substrate.
- the double-sided adhesive tape is applied between the screw head and the substrate.
- the adhesive tape is first applied to the substrate; then the screw is inserted and pressed under pressure against the tape.
