Self clinching fasteners - Import export

The self-clinch nut is a threaded fastener that has a knurl and a notch. The knurl ensures while embedding into the metal sheet the displaced material to spread evenly in the notch. This ensures an especially good stability. Advantages: • high resistance to torque strain • absolutely fl ush sheet metal backsides • compact and clean - ideal for example for use in electronic and light engineering

Self-clinch studs are fasteners that have a serration under the head. At inserting into the metal sheet it presses the displaced material into the rivet ring to secure the fastener. Sheet metal fasteners with internal and external threads are especially suitable for working with thin metal sheets starting with 0.5 mm thickness. This reduces the thickness of the elements in general in favour of lower weight and less material. Aft er processing they are permanently connected to the base material. The screwed connecti ons can be removed aft erwards without risking displacement of the fastener. Through this the production processes are rationalized and secured.

Vacuum El System works with a large variety of fasteners such as Self Clinching Fasteners, Rivet Bushes, Blind Rivet Nuts, Blind Rivets, Cage Nuts, Weld Studs and Inserts for plastics, ranging from ØM3 to ØM12 with cylindrical or hexagonal shape. Both manual and pneumatic tools are used, allowing fasteners to be easily integrated into the manufacturing process.

Self-clinch standoffs can serve as spacers or distance pieces. The hexagon head is simply pressed into the metal sheet, that the material will compress in the nut. The pressing in at the head finishes completely flush. A wide selection of open or closed versions is available. For applications with high strain versions with larger heads and higher compressive tensile strengths can be produced.

Self-clinching rivet nuts from series 10.455 and 10.456 are riveted into the component. A shaft is passed through a pre-punched hole in the component and riveted on the opposite side. The base material is not deformed in the process. These threaded fasteners feature serrated shafts that cut into the metal sheet surface, ensuring a high torsion resistance and torque load capacity. In addition to insertion with the aid of a press, these models can also be inserted using hand tools.

A non-detachable fastening for sheet metals can be produced at optimum cost by using self-clinching screws under the brand names of RIVTEX® (for sheet thicknesses between 0.75 and 2.00 mm) and STRUX® (for sheet thicknesses between 2.0 and 5.00 mm). The clinching technology is suitable for steel and aluminium sheets, causes very little cost in inspection and control, and allows several clinch screws to be processed in a single stroke.

How the fastener functions The material is peeled and a collar formed so that a flush and positive fit of the fastener is created with the sheet metal material. This can either transfer very high forces (e.g. AX 20x14) or with the version that is flush with the sheet, the fastener can be used to directly mount connected parts (e.g. AX 16x4). This principle can be applied to almost every material. The benefits of the RIVORM® HR clinch nut one nut for all sheet metals up to 4.5 mm cost-saving due to fewer variants high-strength, press-hardened and hot-stamped steels very good torsional strength regardless of metal strength high pull-out force The benefits of the RIVORM® TR rivet for fitting ties and springs fully automated processing possible in the subsequent composite tool can be applied universally for different assembly jobs, such as fastening electrical control units, or other plastic parts, simply by clipping them in

TriPress® is a triangular rapid fastening system that can be clinched into plastic and light metals. During the clinching operation, the two components of the TriPress® fastener connect together quickly and economically. It is available in the following designs: Triangular shank and knurl parallel with axis provide greater torsional strength. Circumferential locking flutes on triangular shaft generate high pull-out resistance. Combination of grooves and knurls permit positive-fit fastenings and achieve high torsional torques and pull-out forces (figure 4). So the fastener can be clinched into pre-prepared holes or injected as inserts into plastic housings.
