The nail 6 is driven through the non-preholed components in the joint area at a high speed such that the nail point completely penetrates both components and a material collar, which extends into an adhesive layer between the two components, is only formed in the to driving direction in the nail-head-side component. ## Claims ### Claim 1 A method for establishing a connection between first and second non-pre-holed components in a joint area by a nail having a nail head, a nail shank and a nail point, wherein the component proximate the nail head is the first component and the other component is the second component, the method comprising: a. applying adhesive to at least one of the components so that the adhesive is arranged between the two components in an adhesive layer having a thickness, b. arranging the components spaced from each other, c. positioning the components with a tensioning device, thereby simultaneously setting a specified gap width of a gap between the two components, d. driving the nail in a substantially non-rotating and axial manner into the components in the joint area at a speed in a range of 5- 300 m/s with a setting device, thereby coupling together the two components, by causing the nail point to penetrate both components and forming only a material collar in the first component, the material collar protruding from the first component in the direction facing towards the second component, and extending into the adhesive layer, e. wherein the material collar is disposed on the second component and bridges the gap between the first and second components. ### Claim 2 (depends on 1) The method according to claim 1, wherein the two components are coupled such that the thickness of the adhesive between the two components adjacent to the joint area remains substantially constant. ### Claim 3 (depends on 1) The method according to claim 1, wherein in the step of driving the nail is performed without a ring groove such that the nail head is supported on the first component and the nail head includes a ring surface, defined by an inner ring radius and an outer ring radius, the inner ring radius being larger than an outer radius of the material collar. ### Claim 4 (depends on 3) The method according to claim 3, wherein the inner ring radius is larger than the outer radius of the material collar or greater than a radius of the nail shank. ### Claim 5 (depends on 1) The method according to claim 1, further comprising: applying the adhesive in a locally restricted area to at least one of the components and distributing the adhesive two dimensionally between the first and second components by pretensioning the components with the tensioning device. ### Claim 6 (depends on 1) The method according to claim 1, wherein the step of driving the nail includes setting the nail point so as to completely penetrate the components and protrude the nail point beyond the second component such that a crater-shaped material bulge is formed in the second component, the bulge protruding from the second component. ### Claim 7 (depends on 1) The method according to claim 1, wherein the nail shank is substantially cylindrical. ### Claim 8 (depends on 1) The method according to claim 1, wherein the nail shank converges in the direction of the nail head. ### Claim 9 (depends on 1) The method according to claim 1, wherein the nail shank converges in the direction of the nail head. ### Claim 10 (depends on 1) The method according to claim 1, wherein the nail shank is provided with a surface profiling that fills with displaced material while the two components are coupled together. ### Claim 11 (depends on 10) The method according to claim 10, wherein the surface profiling is arranged only in one area of the nail shank lying within the second component after the components are coupled together. ### Claim 12 (depends on 10, 11) The method according to claim 10 or 11, wherein the ratio of a maximum depth of the surface profiling to an average diameter of the nail shank is less than 0.1. ### Claim 13 (depends on 10) The method according to claim 10, wherein the surface profiling in axial cross-sections includes a rounded, wave-shaped profile. ### Claim 14 (depends on 10) The method according to claim 10, wherein the surface profiling in axial cross-sections consists of a sawtooth-shaped profile. ### Claim 15 (depends on 10) The method according to claim 10, wherein the surface profiling includes a series of circular recesses and rises. ### Claim 16 (depends on 10) The method according to claim 10, wherein the surface profiling includes a thread forming a corresponding counter thread during the step of driving the nail. ### Claim 17 (depends on 16) The method according to claim 16, wherein a pitch of the thread is less than 0.35. ### Claim 18 (depends on 16) The method according to claim 16, wherein the nail head is structured to allow the nail to be removed from the two components. ### Claim 19 (depends on 1) The method according to claim 1, further comprising a profile-free section provided between a part of the nail shank provided with a surface profiling and the nail point. ### Claim 20 (depends on 19) The method according to claim 19, further comprising providing a diameter-reduced section between a part of the nail shank provided with the surface profiling and the nail point. ### Claim 21 (depends on 1) The method according to claim 1, wherein a top side of the nail head is substantially even up to an outer edge of the nail head to transfer setting forces impacting the nail head substantially to the first component in an end position of the nail and to thereby prevent the nail from puncturing both of the two components. ### Claim 22 (depends on 1) The method according to claim 1, wherein the nail point has an ogival form with an ogivality factor of 3 to 5. ### Claim 23 (depends on 1) The method according to claim 1, wherein the nail is a single piece and composed of at least one member selected from the group consisting of steel, aluminum, magnesium, brass, ceramic, and a fiber-reinforced plastic. ### Claim 24 (depends on 1) The method according to claim 1, wherein the shank and head of the nail are composed of materials with different hardnesses and are then coupled together. ### Claim 25 (depends on 1) The method according to claim 1, wherein the second component is a profile component with a greater thickness than the first component. ### Claim 26 (depends on 1) The method according to claim 1, wherein the components are composed of at least one member selected from the group consisting of steel, aluminum, magnesium, and plastic. ### Claim 27 (depends on 1) The method according to claim 1, wherein the nail head is a countersunk head having a bottom side with a diagonally running section such that the countersunk head at least partially punctures the material of the first component. ### Claim 28 (depends on 1) The method according to claim 1, wherein the components are tensioned against each other during the setting process by a hold-down device provided on the setting device or a tensioning mechanism independent of the setting device. ### Claim 29 (depends on 1) The method according to one of claim 1, wherein the step of driving the nail is performed with one single hit from the setting device. ### Claim 30 (depends on 1) The method according to claim 1, wherein the step of driving the nail is performed with one hit from the setting device and the nail is completely driven into the two components with one or more additional hits, the one or more hits being performed manually or mechanically. ### Claim 31 (depends on 1) The method according to claim 1, further comprising: provisioning a nail shank with a sawtooth profile such that each sawtooth tapers towards the nail point. ### Claim 32 (depends on 31) The method according to claim 31, wherein an encapsulating end of the sawtooth profiling and the profile of the nail point include a substantially parabolic progression together in axial cross-sections.
