Types of insert fasteners for self-clinching and welding

We offer the most suitable product type for every application.

  • Self-clinching nuts

    Our self-clinching nut allows you to quickly and economically obtain a strong thread in thin sheet metals.
    Available in zinc-plated steel and stainless steel.
    Simple in installation.
    The self-clinching nut is installed using a press.

    Advantages

    • High resistance to pull-out and tightening torque
    • Strong thread
    • Small body
    • Only protrudes from the support surface
    • The support surface does not damage
  • Threaded studs

    Threaded studs are designed to create a strong male thread in thin-walled parts.

    The head of the stud is completely inserted into the sheet metal and the threaded part remains perpendicular to the material.

    Available in zinc-plated steel and stainless steel.
    Installation is simple.
    The threaded insert stud is riveted using a press.

  • Non threaded studs

    Non threaded studs are used in wide range of applications for positioning or aligning parts.
    The head of the stud is completely inserted into the sheet metal and the smooth part is perpendicular to the material.
    Available in zinc-plated steel and stainless steel.
    Installation is simple.
    The non threaded stud is installed using a press.

  • Standoffs with internal thread

    Standoffs with internal thread enable precise and reliable assembly, separating panels, sheets or assembled components.
    They are inserted into a round hole in the sheet metal by applying constant pressure with a press.
    Available in zinc-plated steel and stainless steel, with open or closed (blind) bodies.
    Open standoffs with internal thread allow the screw to pass through the standoff, while blind standoffs do not.
    Installation is simple.

  • Welding threaded studs

    Welding threaded studs are attached to metal parts by welding.
    Create a reliable male metric.
    Available in copper-plated and stainless steel versions.

    Advantages

    • The metal part, opposite the side where it is placed, remains smooth.
    • Its assembly does not require accessibility on both sides of the sheet metal.
    • The absence of perforations during the installation process guarantees watertightness.
    • Compliant with DIN EN ISO 13918 PT (DIN32501) in M3 to M8.
  • Welding tapped studs

    Welding tapped studs are attached to metal parts by welding.
    Available in copper-plated and stainless steel versions.

    Advantages

    • The metal part, opposite the mounting side, remains smooth.
    • Its assembly does not necessarily require accessibility from both sides of the sheet metal.
    • The absence of perforations during the mounting process guarantees watertightness.
    • Applications: for sheet metal thicknesses ≥ 0.6 mm.
    • They comply with DIN EN ISO 13918 IT (DIN32501) from O 5 to O 7.1.
  • Welding pins without thread

    Welding pins without thread are placed into metal parts by welding.
    They are used in a wide range of applications to position or align the part.
    Available in copper-plated and stainless steel versions.

    Advantages

    • The metal part, opposite the mounting side, remains smooth.
    • Assembly does not require access to both sides of the sheet metal.
    • The absence of perforations during the mounting process guarantees watertightness.
    • They comply with DIN EN ISO 13918 UT (DIN 32501) from O 3 to O 8.
