Riveting technology

RIVKLE® blind rivet nuts

Resilient threads on thin-walled components with RIVKLE® blind rivet nuts and studs.

RIVKLE® blind rivet nuts and blind rivet studs

Load-bearing threads on thin-walled components

Highly resilient

RIVKLE® blind rivet nuts and studs reliably join thin-walled components. Do your components also have thin walls that prevent the use of pre-cut threads? This is where you can use RIVKLE® load-bearing nut or stud threads. Various versions and sizes provide the perfect solution for every application.

Plus factors

Advantages of RIVKLE®

  • One-side assembly

    Simple blind assembly. Often the only solution for hollow bodies, housing or components with access from one side only.

  • Flexible application

    Perfect for every stage of production. No reworking required by your production department after insertion, even for parts that are already coated or painted.

  • No thermal stress

    Unlike when using weld nuts, the workpiece is not impaired by heat.

Method and principle

Using rivets instead of welding

RIVKLE® blind rivet nuts and studs offer versatile solutions for fastening resilient nut/bolt threads to thin-walled components or hollow sections. They are very easy to assemble without counter pressure (i.e. “blind”) in all metal materials, plastics and even in ceramic components. This process is particularly safe since there is no risk of burning and it does not generate harmful steam or gases.

  • RIVKLE® SFC

    You can use RIVKLE® SFC, Smart For Composite, to insert load-bearing threads in plastics and composite materials without damaging them.

    Working principle

    • The basic principle is that the load is specifically distributed in the direction of the thread axle with no radial stress.

    Versions

    • RIVKLE® SFC is available in various versions in steel and stainless steel (A4).

  • RIVKLE® Seal Ring

    To protect your assemblies from external influences, RIVKLE® Seal Ring technology ensures a tight seal against all fluids and gases.

    Advantages

    • The seal is securely bonded to the RIVKLE® blind rivet nut. It remains in place under all circumstances, including during automatic setting with a blow feed unit
    • Tightness in compliance with standard ISO 20653, specification IPX7
    • UV resistance and temperature resistance up to 220°C
    • Resistance to all fluids (oils, hydrocarbons, etc.)
  • RIVKLE® HRT

    Our high-strength RIVKLE® HRT (high resistance thread) blind rivet nuts provide an extremely strong load-bearing thread which considerably improves the mechanical properties of the blind rivet nut. 

    Versions

    • Steel and aluminium

    Advantages compared to RIVKLE® Standard

    • Higher tightening torques permit higher preload forces in the joint
    • Smaller sizes possible
    • Reduced weight
    • Corrosion-resistant and recyclable, particularly in aluminium components (RIVKLE® HRT Aluminium)

  • RIVKLE® PN with slotted shank

    Versions

    • Steel (aluminium and stainless steel on request)

    Advantages compared to RIVKLE® Standard

    • High pull-out forces
    • RIVKLE® PN has the largest clamping range of all blind rivet nuts for variable material thicknesses
    • Large clamping range to reinforce workpiece
    • Low radial stresses during setting prevent excessive loading of the component
    • Low radial stresses in the component
  • RIVKLE® Blind rivet studs

    RIVKLE® blind rivet studs allow you to prefix the screw-on component to the carrier component. This is particularly helpful for heavy or large parts or with concealed assembly (“hang on” assembly). Our blind rivet studs are available in different versions

FAQ

Questions and answers for RIVKLE® blind rivet nuts and studs

Questions can arise by using products. We have answered some of the most common ones for you here. If your question is not among them, please contact us.
  • We manufacture RIVKLE® blind rivet nuts from steel, stainless steel or aluminium

    • Steel: our standard for higher loads
    • Aluminium: lower weight, corrosion resistant
    • Stainless steel: corrosion and temperature resistant
  • RIVKLE® blind rivet nuts and studs create internal threads 7 threads on thin-walled components.

    For hollow bodies, profiles, housings or components with only one-sided accessibility, setting a blind rivet nut is often the only possible solution.

    The industries in which the blind riveting process is used include the automotive industry as well as the mechanical and electrical engineering.

  • Technically speaking, blind rivet nuts, rivet nuts and rivet nuts are the same component. At Böllhoff, we have decided to use the term blind rivet nut throughout for our product.

  • We offer the right design for every application. The differences come in the head shapes, the body ends and the body shapes:

    • Head types: Flat, thin, extra-thin and countersunk
    • Body end: Open and closed
    • Body: Plain, knurled, hexagonal, half-hex and slotted

    In addition, we have special solutions for composites or wood and many more in our portfolio.

    Please feel free to contact us.

  • For setting RIVKLE® blind rivet nuts and studs, Böllhoff offers manual installation tools, mechanical installation tools and automated setting tools. A selection of installation tools are available in the eShop.
