Key Features of Self-Tapping Inserts

  • Self-Tapping Action:
    Designed to cut their own threads as they are screwed into a pre-drilled hole, eliminating the need for separate tapping operations. This simplifies the assembly process and reduces production time.

  • High-Quality Material:
    Typically made from premium brass, these inserts offer excellent corrosion resistance and durability, making them ideal for a wide range of applications, from consumer electronics to automotive and industrial products.

  • Precision Engineering:
    The inserts are manufactured to tight tolerances, ensuring consistent thread profiles and reliable engagement with fasteners.

  • Versatile Application:
    They are especially effective in thermoplastics and other soft materials, providing a metal-to-metal threaded connection that significantly enhances the load-bearing capacity and longevity of the joint.

Applications of Self-Tapping Inserts

  • Manufacturing & Assembly:
    Used in injection-molded parts and assembled components where a durable metal thread is needed in a softer substrate.

  • Repair & Reinforcement:
    Ideal for repairing stripped or worn-out threads in plastics, aluminum, or other soft materials without replacing the entire component.

  • Consumer Electronics & Appliances:
    Ensures reliable and robust fastening in housings, enclosures, and mounting panels.

  • Automotive & Industrial Products:
    Provides long-lasting thread repair and reinforcement in applications subject to vibration and mechanical stress.


Advantages of Self-Tapping Inserts

  • Cost and Time Efficiency:
    Eliminates the need for secondary tapping operations, thereby reducing manufacturing complexity and production costs.

  • Improved Joint Strength:
    Creates a robust metal thread within a softer material, significantly enhancing the load-bearing and wear resistance of the connection.

  • Ease of Installation:
    The self-tapping design allows for quick, tool-free or low-torque installation, making it an ideal solution for high-volume production and repair applications.

  • Reliability:
    Consistent, precision-made threads ensure a secure, permanent connection that withstands repeated use and mechanical stress.


By selecting Conex Metals’ Self-Tapping Inserts, you invest in a reliable, high-performance solution that simplifies manufacturing and enhances the durability of threaded connections in challenging materials.
