Adafruit Heat-Set Insert For Soldering Irons - #4-40 / M3 Inserts

Enhance your 3D printing projects with precision and strength using machine screws and heat-set inserts. These inserts are affordable and feature a grooved exterior with threaded interiors, originally intended for injection-molded parts but perfect for 3D-printed plastics too.

Say goodbye to the hassle of misplaced inserts with these specially-designed tips from Virtjoule. The innovative vertical wall ensures a smooth insertion process, reducing the likelihood of the insert sticking to your soldering iron. Unlike conical tips, the square shoulder aids in precise alignment, ensuring your insert remains perfectly square in your project.

Compatible with ATTEN 65W and 50W soldering irons, this unique accessory transforms your soldering iron into an efficient tool for embedding heat-set inserts. Simply attach the part, heat the iron, press the insert into place, and let it cool. The result is a robust, embedded hex nut ready for use.

This tip accommodates #4-40 or M3-sized inserts, with no soldering iron or inserts included. It's compatible with any iron using Hakko tips, though a slight looseness during installation is normal. Functionality remains uncompromised, providing an effective solution for your project needs.
