          L3824 Self-tapping Threaded Inserts

          L3824 Series Threaded Inserts

          The advantages: 
          Efficient installation process resulting from additional driver shape (e.g. hexagonal shape)
          For thermoplastics and thermosets
          Extra small flank angles of the special external thread
          minimise radial tensions
          High-strength and torsion-proof threads
          Special version available with external left-hand thread for improved reverse locking

          Principle:
          Hex consists of a cylindrical basic body with internal thread and additional internal hexagon and a special external thread. 
          The profile of the external thread has an extremely small flank angle and expands asymmetrically towards the thread root. 
          This way, installation at low driving torques is optimised. 
          Very good tight-fit is achieved with an ideal distribution of load. 
          The bottom part of the bush is provided with a cutting slot.
          For special requirements, we offer a version with flange.
          The threaded bush is inserted and screwed in with a rotating spindle.It is not necessary to screw out the spindle.

          Q1: What are the main advantages of these threaded inserts?
          A: These inserts offer several key benefits:

          • Efficient installation enabled by additional hexagonal driver shape

          • Compatibility with both thermoplastic and thermoset materials

          • Extra-small flank angles on the external thread minimize radial tension

          • High-strength, torsion-resistant threads for reliable performance

          • Special versions available with external left-hand thread for enhanced reverse locking capability

          Q2: How does the design principle work?
          A: The insert features a unique design:

          • Cylindrical body with internal thread and internal hexagon drive

          • Special external thread with extremely small flank angle

          • Asymmetrical thread profile that expands toward the root

          • Cutting slot at the bottom of the bush

          • Optional flange version for special requirements

          Q3: What makes the installation process efficient?
          A: Installation efficiency comes from:

          • Hexagonal drive allows easy tool engagement

          • Low driving torque requirement due to thread design

          • No need to unscrew the spindle after installation

          • Rotating spindle installation method

          Q4: How does the thread design minimize radial tension?
          A: The extremely small flank angles of the special external thread:

          • Reduce expansive forces during installation

          • Minimize stress on the host material

          • Prevent cracking in delicate applications

          Q5: What applications are these inserts suitable for?
          A: These self-tapping threaded inserts are ideal for:

          • Thermoplastic components

          • Thermoset materials

          • Applications requiring high-strength threads

          • Situations where reverse locking is critical

          Q6: Are special versions available?
          A: Yes, we offer:

          • Standard versions for most applications

          • Special versions with external left-hand thread for improved reverse locking

          • Flanged versions for additional bearing surface

          Q7: What installation equipment is required?
          A: Installation can be performed using:

          • Standard hex drivers

          • Rotating spindle equipment

          • No special unscrewing equipment needed
