Product descriptions

  • Product specifications
  • Product characteristics
  • Installation procedures

  • Clamping effect directly in the thread – elastically resilient
  • Even clamping torque in repeated screwings
  • Constant thread friction
  • Uniform load and stress distribution
  • High temperature resistance
  • Modular design
    – Profitable
    – Material and surface in higher quality only required for small fastener (HELICOIL® screwlock)

Locking of the screw is achieved by one or several polygonal-shaped threads on the HELICOIL®. These threads clamp the flanks of the screwed-in screw; the result is an elastically resilient frictional locking. The achieved locking torques can be compared to the indications in ISO 2320.
