SPREDSERT



SPREDSERT® 1

Technology
  • For thermoplastic components
  • Retaining flange and anchor rings provide a high degree of safety against distortion and tensile loads
  • Screw gripping
    Material: Cu Zn 38 Pb 2
Principle
The SPREDSERT® 1 is inserted into the locating hole until the retaining flange is fully anchored in the plastic. At the same time, the slotted section is forced together. The screw forces the radially secured SPREDSERT® 1 open causing the anchor rings to bite into the plastic and ensure a firm hold of the threaded insert. Screw locking is also achieved via this process. The tightening torque is to be increased by 10% for the additional expansion force.
