SNAPLOC® The system SNAPLOC® is a two-piece system consisting of ball stud and coupling. Joining occurs easily by plugging in and disassembly by pulling apart. Since no additional tool is needed, the assembly time is reduced significantly. SNAPLOC® is based on the simple principle of a snap connection. The coupling is installed in the designated mounting geometry on the component to be mounted, thus creating a positive connection. Inside the coupling there is a ball socket which the ball stud as the counterpart can snap into. The ball stud is installed on the mating component. What is special...

SNAPLOC® ball studs are available in six basic designs. They may be distinguished in the form of their fastening: ■ Ball studs with external thread ■ Ball studs with internal thread ■ Ball studs with K' in K' (plastic in plastic) thread ■ Ball studs in clip form ■ Ball studs for injection moulding ■ Ball studs for insertion SNAPLOC® ball studs with external thread The ball studs with metallic external threads are available in different thread forms. These include for example metric threads, American/British threads, self-tapping threads etc., according to the corresponding standards or special...

Ball studs in solid plastic SNAPLOC® K’ in K’ ball studs for direct screwing These SNAPLOC® K’ in K’ ball studs can be screwed directly into plastic components – K' in K' = German for: plastics in plastics (Kunststoff in Kunststoff). Our developed and patented K' in K' thread forms or cuts a holding thread into a cylindrical drill‑hole. Due to the special thread form of the K’ in K’ thread, the screw is locked against loosening. In combination with the receiving component, a self‑locking device is realised. The specialty: To unscrew the thread, a higher torque is necessary than during installation....

SNAPLOC® The variants of the system Coupling SNAPLOC® couplings are available in three basic designs. They vary in the type of fastening: n Couplings for mounting dome with collar n Couplings for mounting dome without collar n Couplings for plate fastening Four product variants are currently available which are defined through the characteristic main feature of the ball stud: the ball head diameters in 7, 8, 10 and 15 mm. The following parameters are variable – external diameter, collar, collar depth, material, colour and ther special designs. The couplings may be combined, in all ways, with...

SNAPLOC® couplings for plate fastenings Due to the geometry, these couplings may be mounted by simply being pushed into a specified bore or square opening. The couplings can be assembled by pressing them easily into a mounting geometry. To simplify the assembly, we offer an installation tool. Example: view of assembled condition SNAPLOC® angular coupling Partially, the insertion direction of the connection and the fastening level are not arranged to each other in a right angle. Especially for the complex shaped parts with the free formed surfaces, it is not easy to generate these surfaces. To...

SNAPLOC® The variants of the system SNAPLOC® couplings with multi-retainer Advantage of the universal mounting geometry: simply being pushed in axial direction or inserted from side into the mounting. Due to the new special part geometry of the couplings, new standards are set regarding the ease of assembly. The benefit is the possible fastening in mounting domes (side insertion) as well as in plate fastenings (easy push-in). SNAPLOC® silicone couplings Silicone couplings (VMQ) are used for applications with special requirements on temperature resistance. By the use of solid silicone, higher...

Depending on the thermal and mechanical requirements, as well as fluid resistance, crosslinked elastomers/rubber or thermoplastic elastomers are used in injection moulding. ■ Very good compression set ■ Good resistance to chemicals ■ Good resistance to mineral oils and greases Silicon on solid or liquid base ■ Excellent compression behaviour ■ High temperature resistance ■ Low influence of temperature changes on mechanical characteristics Elastomer processed by vulcanising ■ Very good compression set ■ Good resistance to chemicals ■ Good resistance to mineral oils and greases ■ High temperature...

The Shore hardness defines the material hardness of elastomers and rubber elastic polymers. Depending on the requirements for thermal and mechanical properties as well as media resistance, cross-linked elastomers/rubber or thermoplastic elastomers are used for injection moulding of SNAPLOC® couplings. In general, there is a strong interdependence between the temperature and the forces to transmit. Overall, the used materials have a diverging thermal behaviour (see figure). EPDM-X+PP and peroxide-cured EPDM show a changed disassembly force for different temperatures. The silicone materials, however,...

SNAPLOC® Installation tool for plate fastening During the pushing of a SNAPLOC® coupling into a drill-hole, the coupling is compressed. Therefore, the assemby can be varied at different Shore hardnesses or geometries. By using an installation tool, the coupling is stretched during the assembly, so that it is tapered in the outer diameter. This aids the assembly. A complete installation tool consists of a handle, a nozzle and a shaft according to the required SNAPLOC® ball diameter.
