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 %.

• For thermoplastic parts
• Knurled flange and anchor rings ensure high degree of security against twisting and tensile load
• Screw locking
