About this item

- Knurled Anti-Slip Design: External knurling increases friction during thermal embedding. Prevents loosening under high torque. Ensures secure, vibration-proof threads in plastic parts.
- Heat-Activated Installation: Simple thermal embedding via soldering iron (not included). Melts smoothly into plastics without workpiece damage. Ultrasonic compatible for industrial use.
- Plastic-Specific Application: Optimised for 3D prints, toys, and plastic housings. Not for metal. Ensures robust internal threads in electronics, medical devices, and automotive parts.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
