Fastening technology for sheet metals and plastic materials

RIVNUT® blind rivet nuts and studs for North American-Inch/Metric sizes are the most versatile solution for fastening high-strength nut or bolt threads to components when tapped threads are not possible due to small wall thicknesses.

Characteristics

RIVNUT® blind rivet nuts and studs

For internal and external threads of components with small wall thicknesses, Böllhoff offers RIVNUT® blind rivet nuts and studs. These elements are mounted without counter pressure ("blindly") and can therefore also be set at hollow sections.
RIVNUT® blind rivet nuts and studs are available in many variations and sizes and therefore offer numerous fastening solutions with additional functions.

Technology

Blind rivet nuts

RIVNUT® blind rivet nuts and studs can easily be used in metal or plastic components as well as in many other material combinations.
Often for hollow bodies, profiles, housings or components with one-sided accessibility, the economical setting of the blind rivet nut and stud is the only possible solution.

Benefits

  • Stable thread on thin-walled components
  • Installation in case of one-sided accessibility (blind assembly)
  • 2 functions (riveting and screwing)
  • Flexible application for every production step
  • The workpiece is not exposed to thermal stress.
  • Low capital expenditure

Setting

Example of a spindle lifting procedure

Here, the RIVNUT® blind rivet nut and stud is spinned on, upset and afterwards spinned off.

  • Large clamp area
  • Great variation of component thicknesses with a blind rivet nut
  • Low radial tensions within the component

Summary

  • Large backside flange diameter for high pull-out loads
  • Slotted body for the widest available grip range
  • Ideal for plastic and thin sheet applications
  • Available in steel, stainless steel, aluminum and brass
RIVNUT® - RIVKLE® (European design for "true metric" hole sizes)
RIVNUT® / RIVKLE® blind rivet nuts and studs

The RIVKLE® product line features the standard European design for “true metric” hole sizes. As a global company, we are able to offer a wide variety of styles and thread sizes. We are also able to offer the RIVKLE® line in a number of materials including steel, aluminum and stainless steel.

Summary

  • European design for "true metric" hole sizes
  • Wide variety of styles and thread sizes
  • Available in steel, aluminum and stainless steel
RIVNUT® TW (Thin wall)

The TW (thin wall) line is designed as a lower cost alternative for applications with reduced load requirements, and with a wider grip range. The Böllhoff TW line is compatible with both spin-spin and spin-pull tooling. Our offering includes the standard head, low profile head and half hex variety.

Summary
