SPREDSERT®

SPREDSERT 1 AND 2
The SPREDSERT® 1 AND 2 are 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 AND 2 are 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 %.
The advantages:

* For thermoplastic parts

* Knurled flange and anchor rings ensure high degree of security against twisting and tensile load

* Screw locking

Material: Cu Zn 38 Pb 2 (EU 2000/53 compliant)

SPREDSERT WITH RETAINING FLANGE
The SPREDSERT® with retaining flange is inserted into the through hole until the retaining flange is seated. The slotted anchoring section with diamond knurl is compressed. By screwingin the screw, the thread insert is forced open in the anchoring section so that the diamond knurling penetrates the plastic material. The retaining flange which acts as a shoulder support ensures high pull-out locking while the screw is also locked. For the additional expansion force, the tightening torque must be increased by 10 %.

The advantages

* For thermoset and thermoplastic components

* High-strength threads in through holes

* Screw locking
