Fasteners of our own development and production

In an environment of ever changing requirements we support our customers as experts in the most diverse fields of fastening technology. Together we develop innovative solutions for current requirements and materials of the future.

Rivet technology


    RIVSET® rivets

    RIVSET® self-pierce riveting is a process for high-strength mechanical joining of similar materials or material combinations. In this process several layers can be joined easily.

  • Blind rivet nuts

    RIVNUT® / RIVSTUD® blind rivet nuts and studs

    Blind rivet nuts and RIVSTUD® blind rivet studs are the most versatile solution for fastening high-strenth nut or bolt threads to components when tapped threads are not possible due to small wall thicknesses.

  • RIVKLE® blind rivet nuts – range kits

    RIVNUT® blind rivet nuts – range kits

    The setting of RIVNUT® blind rivet nuts is often the only fastener solution for hollow sections, housings or where access is limited to one side of a component for adding a thread to thin-walled workpiece.

    Böllhoff Repair Solutions - RIVNUT® plus

    RIVQUICK® blind rivets

    For years, RIVQUICK® blind rivet technology has proven to be a reliable method for non-detachable joining of thin-walled components.

High-speed joining


    RIVTAC® High-speed joining

    The innovative joining technology with the fully automatic system for stored feeding is suitable for plenty of material combinations.

Thread technology

  • IMTEC® Moulded inserts for plastics

    IMTEC® Moulded inserts

    IMTEC® refers to the „In-Moulding TEChnology“ and describes the in-moulding of metal thread inserts with plastics before ejection.


    ONSERT® Adhesion of fasteners

    Quick and process-safe adhesion

    The ONSERT® technology allows adhesion of different fasteners to diverse materials.

  • UNITEC® K' in K'

    UNITEC® K' in K' plastic fasteners for plastics

    Screwing solutions made of plastic for plastics

    The K' in K' system was especially developed by us and is characterised by special thread profiles. The different system variants are self-locking, self-tapping, self-forming, adjustable and tolerance-compensating.

    UNITEC® K' in K'
  • AMTEC®

    AMTEC® thread inserts

    Highly wear-resistant thread inserts for plastic parts

    AMTEC® stands for "After Moulding TEChnology" and refers to the installation of brass thread inserts into plastic components after moulding.


    KOBSERT® thread inserts

    Thread reinforcement in metals

    KOBSERT® threaded bushes are the ideal solution for creating highly wear-resistant, vibration-resistant and torsion-proof nut threads in metal low-strength materials.

  • HELICOIL® lock nuts

    HELICOIL® nuts

    Special nuts with screw lock

    HELICOIL® locknuts are a combination of high-strength nut bodies and HELICOIL® thread inserts.

    HELICOIL® locknuts
  • SEAL LOCK® sealing nuts

    SEAL LOCK® sealing nuts

    Sealing of bolt-nut joints

    SEAL LOCK® sealing nuts are an economical solution for reliable sealing against gaseous and liquid media under high pressure.

Vibration and noise decoupling


    SNAPLOC® plug-in connections

    Vibration and noise-decoupling fastening system

    The two-component SNAPLOC® fastening system consists of a ball stud and a coupling for fast installation and is based on a simple snap connection.

  • RIVNUT® AV – Blind rivet nuts for vibration and noise-decoupling


    Vibration and noise-decoupling fastening element

    RIVNUT® AV is a detachable blind rivet joint with vibration and noise-decoupling function.

Tolerance compensation


    FLEXITOL® automatic tolerance compensation

    FLEXITOL® tolerance compensation systems have been designed to compensate tolerances by economical installation solutions and thus to ensure a secure process in series productions.

Quick-release technology

  • QUICKLOC® Quick-release fasteners

    QUICKLOC® quick-release systems

    QUICKLOC clamp, rotation and pressure locks are especially suitable for repeatedly detachable joints and quick assemblies.
