Barb-Serts® - Key Features:

Barb-Sert threaded inserts provide superior pull-out and torque resistance in thermoplastics, making them a popular choice for molders.

  • Designed for use with thermoplastics.
  • Superior pull-out and torque resistance.
  • Suitable for push-in, ultrasonic or heated installations.

Barb-Serts are made of solid brass in regular or short length.

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

Unique exterior barb pattern makes it possible to install Barb-Serts into straight or slightly tapered holes using a variety of methods such as push-in, ultrasound or heat.

Barbs displace and capture plastic base material during installation to firmly lock the insert in place.

The pilot ring eases orientation and guides installation. Headed versions are also available.

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