Press-In Locking Insert
For Thermoplastics
This insert is designed especially for press-in installation into most thermoplastics.
Utilising a combination of sharp radial fins, knurled fins and straight cut knurls to provide easy press-in installation whilst achieving good torque-out and pull-out performance. The expansion feature of this insert also provides a locking action on the thread.
For best performance we recommend a pre-moulded hole with a 1° taper (the hole diameter specified should be met at the point reached by the bottom of the insert).
Screw length should be long enough to fully penetrate the insert to give full expansion and achieving optimum performance.
Installation into notch sensitive plastics is not recommended.
