This Ruthex threaded insert assortment provides M2, M3, M4, and M5 brass nuts specifically designed to create stable, durable, and reusable screw threads in 3D printed thermoplastic parts.

Key Features

Crafted from high-quality brass, the inserts offer optimal corrosion resistance and excellent thermal conductivity. Their unique geometry features opposing spiral-shaped knurls, ensuring a firm grip, high tightening/loosening torque, and superior tightening force. An integrated guide simplifies the insertion process.

Installation & Compatibility

The inserts are easily installed into 3D printed components using heat (such as from a soldering iron) or ultrasound. They are suitable for embedding into both blind and through holes. Compatible with all common thermoplastics, including PLA, PETG, ABS, PPS, and PP, the knurled nuts anchor securely once the surrounding plastic cools. The inserts are also reusable and delivered in a practical assortment box for organization.
