Description
The SPREDSERT® 1 is inserted into the mounting hole until the retaining flange is completely anchored in the plastic material. In that process, the slotted area is compressed. The radially secured SPREDSERT® 1 is expanded by the screw so that the anchor rings penetrate the plastic material and ensure the tight-fit of the thread insert. In this process, the screw is locked. For the additional expansion force, the tightening torque must be increased by 10%.
