          Exp-Loc Inserts

          ELH2 Series Inserts

          The advantages:
          Easy press in insertion
          Self locking action on the screw,ideal for where vibration
          Press-fit insert with strong,reusable threads.
          No heat or ultrasonics required.
          Flange-head eliminates direct contact of plastic with mating parts.
          Slotted insert compresses allowing easy access into the mounting hole.
          Suitable for most thermosetting plastics,Exp-loc are press-in expansion inserts which,due to Exp-loc diamond knurl pattern,give minimum penetration of the sides of the hole without sacrificing pull-out resistance.        

          Installation instruction: 
          Influence of screw dimensions
          It is important that the fixing screw fully penetrates the insert in order to achieve full expansion,screw length should therefore be calculated to ensure that this condition is met before final clamp torque is applied.

          Q1: What are the main advantages of Exp-Loc press-in expansion inserts?
          A: Exp-Loc inserts provide multiple benefits:

          • Quick and tool-friendly press-in installation

          • Self-locking screw retention, ideal for high-vibration applications

          • Durable, reusable internal threads for reliable fastening

          • No heat or ultrasonic equipment required for installation

          • Protective flange head prevents damage to mating plastic surfaces

          • Slotted design allows compression for easy insertion into mounting holes

          • Compatible with most thermosetting plastics

          • Diamond knurl pattern minimizes radial stress while maintaining high pull-out resistance

          Q2: How should Exp-Loc inserts be properly installed?
          A: The key installation requirement is ensuring the fixing screw fully penetrates through the insert. This complete penetration is necessary to achieve full expansion of the insert and proper locking functionality. Always verify screw length meets this requirement before applying final torque.

          Q3: What happens if the screw is too short during installation?
          A: Insufficient screw length will prevent the insert from achieving full expansion, resulting in reduced holding power, compromised thread integrity, and potential fastening failure in the application.

          Q4: Are these inserts suitable for vibration-prone environments?
          A: Yes. The Exp-Loc design features a self-locking mechanism that effectively resists screw loosening under vibration, making these inserts particularly suitable for dynamic applications.

          Q5: Can Exp-Loc inserts be used with thermoplastic materials?
          A: These inserts are specifically engineered for thermosetting plastics. For thermoplastic applications, please consult our technical support team for alternative solutions.

          Q6: What equipment is needed for installation?
          A: Exp-Loc inserts can be installed using simple pressing equipment, making them suitable for both manual assembly and automated production environments.
