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.
