          DLH Inserts

          DLH Series Inserts

          The advantages:
          Universal thread insert for thermoset and thermoplastic components
          High-strength threads by expansion anchoring
          Quick, cost-effective installation           

          Installation instruction:
          The DLHS thread insert consists of a cross-slotted basic body with internal thread, 
          which has an external diamond knurl, and an spreader plate.
          When the thread insert is installed in the mounting hole, 
          the diamond knurl part is expanded by the spreader plate which is pressed down.
          As a result, it is anchored in the wall of the hole.

          DLHS-Threaded Inserts For Metal-data


          Q1: What are the main advantages of the DL Thread Insert?
          A: The DL Thread Insert offers several key benefits:

          • Universal compatibility with both thermoset and thermoplastic components

          • Provides high-strength, reliable threads through expansion anchoring

          • Enables quick and cost-effective installation

          Q2: How is the DL Thread Insert constructed?
          A: The insert consists of three main components:

          • A cross-slotted basic body with precision internal thread

          • An external diamond knurl pattern for enhanced grip

          • A dedicated spreader plate that activates the expansion mechanism

          Q3: How does the installation process work?
          A: During installation:

          1. The insert is placed in the prepared mounting hole

          2. The spreader plate is pressed downward into the insert body

          3. This action expands the diamond knurl section radially outward

          4. The expanded knurl creates a secure, permanent anchor in the hole wall

          Q4: What types of materials are compatible with these inserts?
          A: These inserts are specifically designed to work with both thermoset and thermoplastic materials, making them suitable for a wide range of applications.

          Q5: Why is the diamond knurl pattern important?
          A: The diamond knurl pattern provides superior grip and resistance to rotation when expanded against the hole wall, ensuring maximum pull-out strength and torque resistance.

          Q6: Are special tools required for installation?
          A: Standard pressing equipment can be used to activate the spreader plate mechanism. The cross-slotted design also accommodates various installation tools for different production environments.

          Q7: What makes this installation method cost-effective?
          A: The simple press-in installation requires no heat, solvents, or complex equipment, reducing both installation time and required labor resources.
