A heat-set threaded insert has two important features. The inside of the brass piece of hardware has a nice, threaded thru the hole.

The exterior has ridges, so when installed using heat, the plastic can easily flow around and then solidify. Once solidified, the insert is in place, making it resist torque and pull-out.

Installation:

Tools you need:

1. Heat-set threaded Insert Nut

2.  Plastic Body Part

3. Soldering Iron

Preparing the threaded insert:

Use the soldering iron on a low setting to preheat the threaded insert using a shallow tapered soldering iron tip.

Feature:

1. Heat-Set is designed specifically for notch-sensitive plastics
2. Expansion-Sets offer simple press-in installation
3. Flow-Sert is a blind insert for installation during the moulding process
4. Brass Material Can Resist Heat.
5. Not Easy to Rust, Strong Corrosion Resistance.
6. Very high pull-out and torque resistance.
7. Can be installed by ultrasonic or Heat into thread tapered hole, or moulded in during injection.
8. No need to counterbore or countersink the boss hole since the insert has guide pilot.
9. Used on the injection moulding for tightly fixing.
