Projekt otworu dla PUSHTITE® II™

In order to ensure a safe installation, it is relevant to pay attention to the boss design, as it must resist mold extraction and cooling tension as well as tension created during screw installation.

It’s important to include a relief bore to prevent damaging the boss when starting thread forming. The relief bore also helps to align the screw during threading.

The dimensions for external diameter, core hole diameter and minimum depth will vary based on the type of plastic.

This data is intended for guidance purposes. We recommend carrying out relevant tests on plastic parts to establish the precise values.
