Threaded Inserts > Specifications > Vibra-Sert® I and II

Vibra-Sert® - Key Features:

Vibra-Sert inserts are installed with ultrasound to produce high torque resistance and good pull-out resistance in thermoplastics. Vibra-Sert I inserts are to be used in straight or slightly tapered holes. Vibra-Sert II inserts are designed specifically for use in tapered holes.

  • Superior torque resistance.
  • Designed for use with thermoplastics.
  • Provides a clean surface finish.

Vibra-Sert I

Exterior knurls combined with knurl channel design capture plastic base material during installation and lock the insert in place.

High-quality internal threads are wear resistant, Unified and American Standard, class 2B, or ISO Metric standard, class 6H threads.

Vibra-Sert II

The top flange directs molten plastic downward leaving a mar-free surface.

Exterior knurls combined with knurl channel design capture plastic base material during installation and lock the insert in place.

The pilot ring eases orientation and guides installation.

Vibra-Serts are made of solid brass in regular or short lengths. Headed versions are also available.
