Blind rivet nuts and studs for the automotive industry

The blind rivet nut and stud technology can be configured as you wish and tailored to the required environment. Our experts will assist you in designing the fastener that will meet your requirements by carefully selecting the beneficial product characteristics (head shape, material, body end). The standard product line offers many variants. It is possible to change the attributes of a nut or a stud so that it can be integrated into your automotive application (e.g., Surface plating).

Based on the increasing demand for gas- and watertight fasteners with threads, J-X developed a closed-end blind rivet nut with an additional seal made of automotive Certi fi ed material that combined these requirements with the advantages of economic and process-secure machining. The sprayed and embedded seal on the bottom of the head guarantees a much better form closure than conventional o-rings. The hexagon shaft avoids any risk of rotation and offers higher clamping forces. An additional large head with a significant bearing allocates the forces on soft materials equally. Seal the nut with a molded-on captive plastic seal. It is used on car boot hinges to provide a pressure-tight connection.

Seal Ring Function： Ensures leak tightness with pressurized or non-pressurized liquids. Characteristics： 1. Seal placed in a groove under the head 2. Possibility of resistance to different environments (temperature and product) 3. Resistance level in compliance with standard ISO 20653, IPX7

As your partner in the development and manufacture of fastening systems, we develop a large number of application-specific, purpose-designed fasteners. Our work is carried out under the quality standards ISO 9001. This is intended only to give you additional functionality from spray-on plastic parts, pre-assembled mechanically joined components, glued or welded parts, etc.

The combination of a knurled body with ribs under the head allows you to optimize the anti-turn resistance of your assemblies on soft materials—a more muscular anti-turn function.

With knurls on the body and under the extra-large head, this fastening improves mechanical properties in soft workpieces. Guarantees the best match of blind rivet nuts to plastic workpieces. Zinc-nickel surface treatment provides optimum corrosion resistance.
The hexagonal body, thread For fastening motor vehicle safety belts, increased resistance to turning, very high mechanical loading capacity, and a zinc-nickel surface treatment provide optimum corrosion resistance.

Decide with the following selection guide which innovative principle of the molded inserts is particularly suitable for your requirements. With double flange, rivet nuts are produced from steel by cold forming. The deformation area allows precise adjustment of the length of the thread insert according to the mold size. Upon closing, the mold parts compress and precisely adjust the length of the component (L ± 0.15 mm).

The thread inserts with double flange rivet nuts are produced from steel by cold forming. The in-molding technology requires remarkably accurate thread inserts. The deformation area allows for precisely adjusting the length of the thread insert according to the mold dimension. Upon closing, the mold parts compress and precisely adjust the component size (L ± 0.15 mm). It is primarily intended for components with through-hole threads.

Benefits: ● Huge flange diameters possible ● Deformation area for length adjustment of the insert; close length tolerances < L ± 0.05 mm ● Torque resistance by hexagonal design or knurls ● Pull out resistance by providing significant undercuts ● No metal-cutting operation ● Also feasible as a compression limiter

Advantages

1. Huge flange diameters are possible

2. Torque resistance thanks to hexagonal design/knurling

3. Generated undercut provides resistance to axial pull-out

4. No metal-cutting operation

5. Can be used as spacer bushing

The deformation area allows for length adjustment of the insert according to the dimension of the mold.

Closed-end versions and different diameters (M 4 to M 12) are available on request:

● Length of component: 10 to 25 mm for M 6 and 10 to 30 mm for M 8

● Tolerance concerning the length: ± 0.15 mm

● Head diameter: 12 to 20 mm

Tooling costs to be considered.
