Embodiment Construction

[0017] Such as figure 1 As shown, the screw element 10 according to the invention consists of a plate-shaped head 12 and a cylindrical threaded carrier 14 connected thereto.

[0018] Between the thread and the head 12, a sizing constriction 16, an annular projection 18 and an annular groove 20 having a substantially semicircular cross-section are arranged in this order. On the bottom side of the head 12, i.e. on the side facing the metal plate during the assembly of the fastener, there are arranged radially extending webs 22, the height of these webs 22 being substantially the same in the direction of radial extension , only the radially outer region 21 is flattened.

[0019] The head 12 is shown partially cut away, the right side of the corresponding slat 22 is also shown cut away, while the left side of the corresponding slat 22 is not cut away.

[0020] According to the present invention, by coating the head with a rubber-like elastic sealing material, it is possible to f...

Abstract

Disclosed is a bolt ( 10 ) that can be pressed into a metal sheet in a torsion-proof and ejection-proof manner and comprises a head ( 12 ). The side of the head ( 12 ) facing the metal sheet after being inserted is provided with radially arranged webs ( 22 ) which are pressed in when being inserted into the metal sheet. A cylindrical winding support ( 14 ) is disposed in the center of the head ( 12 ). Said winding support ( 14 ) extends through the metal sheet and protrudes on the other side thereof while being provided with a circumferential annular groove ( 20 ) near the side of the head ( 12 ) that faces the metal sheet in the set state. The sheet metal material that is displaced during the setting process can be pressed into said annular groove ( 20 ). All or part of the side of the head ( 12 ) facing the metal sheet is provided with a rubber-elastic sealing material ( 110 ).

Description

technical field [0001] The invention relates to a threaded part according to DE-Gbm 20012097 U1 which can be pressed into a sheet metal in a torsion- and withdrawal-resistant manner. Background technique [0002] According to this reference, in the process of screwing the screw into the metal plate, the flow of the metal plate material is accompanied, however, the seal is only composed of steel-steel material pairing, so, in this prior art, the screw and The connection between the metal plates cannot be guaranteed to be liquid-tight or gas-tight. Contents of the invention [0003] Therefore the basic task to be solved by the present invention is to develop a screw, which is in a liquid-tight or even air-tight state when in use. [0004] In this way, according to the invention, it is achieved for the first time that such a screw that can be pressed in can be used where it is necessary to make the screw absolutely liquid-tight and gas-tight after assembly. [0005] For thi...
