COIL "cone"

The new HONSEL COIL "cone" is a tabless wire thread insert that combines the properties and advantages of the HONSEL COIL "free" and HONSEL COIL "plus".

The HONSEL COIL "cone" can be installed in the same way as a coil with tab. No additional or special tools are required for process-reliable installation.

When the HONSEL COIL "cone" is screwed onto the installation spindle, the conical portion of the wire thread insert creates a clamping effect between the installation tool and the coil. This ensures a stable installation process into the work piece.

The HONSEL wire thread inserts consist of special shaped cold-rolled stainless steel wire, which is wound to form a spring-loaded spiral. When installed, the HONSEL COIL "cone" results in a wear free, true-to-gauge internal thread up to 0.5-1.5 threads from the end due to the conical shape.

Advantages

  • tab-free and therefore optimally designed for e-mobility due to no risk of tab debris.
  • Shallower blind hole depths can be realized
  • Subsequent processes are no longer necessary (breaking and removing of the installation tab)
  • No thread skipping during installation
  • Cycle time reduction of 20-30 % per installation
  • No special tools required for the installation process
  • The installation process improves due to the conical portion
  • The installation process can be fully automated with our HONSEL coil screwing system 2G. Available as a complete system „RIWO Coil 2G“: Feeding, screwing technology and control Siemens S7 incl. 3D visualization.

Downsizing

The current trend towards lightweight construction with aluminum and magnesium materials, etc. requires improved solutions for secure fastening. The HONSEL COIL "cone" is right in line with this trend. The HONSEL COIL "cone" ensures a significant thread reinforcement and high resilience in a smaller space. This means that high-strength screws can be used in materials with lower shear strength. The result are significant material and weight savings for the customer component.
