Use Cases

Add threads to plastic components

Use press inserts when a thermoset plastic part needs a threaded fastening point for compatible hardware. They support assembly, fabrication, replacement, and repeat installation needs.

How to Choose

Match the thread and profile

Start with the required fastener thread, then choose a flush, flanged, or reverse-slot configuration that matches the planned insert style. Confirm the insert is intended for thermoset plastic.

Applications

For commercial assembly and fabrication

These inserts are suited to assemblers, fabricators, and commercial users adding threaded attachment locations to thermoset plastic parts.

Planning Guide

Plan the right fit before choosing

Thread Selection

Select the thread required by your compatible fastener

The first selection step is identifying the thread needed for the connection point. The represented range includes inch and metric thread sizes for different fastening requirements.

  • Inch sizes include 6-32, 8-32, 10-24, 10-32, 1/4-20, 5/16-18, and 3/8-16.
  • Metric sizes include M4-0.7 and M6-1.0.
  • Match the insert thread to the compatible fastener or hardware planned for the assembly.
Insert Profile

Choose a flush, flanged, or reverse-slot design

Profile affects the specified configuration of the installed insert. Flush inserts are intended to sit flush or level with the part surface, while flanged inserts include a flange at the installation surface. One represented brass option uses a reverse-slot design.

  • Choose flush profiles where a level installation profile is required.
  • Choose flanged designs when the assembly calls for a flanged insert configuration.
  • Choose a reverse-slot insert when that specified configuration matches the application.
