Further information

Press-Sert Information for designers

The Press-Sert is a press-in insert, designed for post mould installation into thermoplastics. The combination of plain and knurled vanes provides good levels of pull out and torque resistance.

Advantages:

Simple, press-in installation

Provides self-locking action on mating screw

Good pull out and torque resistance

Installation Data

The Press-Sert should be installed with a press that can provide a steady squeezing action to prevent damage to the mating boss. 

The mating screw should always be installed into the knurled end of the insert to allow it to expand. It is important that the screw fully penetrates the insert to achieve full expansion and optimum pull-out resistance.

Press-Sert inserts should not be used in notch-sensitive plastics.
