Brass Heat-Set Threaded Insert Nuts Kit for 3D Printing & Plastic Injection
Create strong, durable metal threads in 3D-printed parts and thermoplastic enclosures with this high-precision brass heat insert nut set. Designed for heat-set or ultrasonic embedding into PLA, ABS, PETG, and acrylic, these knurled threaded inserts provide superior resistance to pull-out and torque-out forces.
Key Features
- High Thermal Conductivity Brass: Premium solid brass construction transfers heat quickly from soldering tips for smooth, precise melt embedding into plastic.
- Dual-Spiral Knurled Exterior: Opposite-direction spiral knurling delivers exceptional torque and pull-out resistance when embedded into cooling plastic.
- Clean Precision Threads: High-precision metric threads allow smooth bolt engagement without binding or cross-threading.
- Ideal for 3D Printing: Perfect for adding reusable machine threads into custom 3D prints, drone frames, PCB housings, and electronics enclosures.
- Easy Heat-Set Installation: Installs effortlessly using standard soldering iron heat-set tips or ultrasonic press equipment.
- Multiple Kit Size Options: Available in convenient 80-Piece, 220-Piece, and 270-Piece assorted box sets covering M2 to M6 thread diameters.
