Brass Heat Set Threaded Insert Nuts for 3D Printing and Plastic

Create stronger, reusable threaded connections in plastic parts with brass heat set inserts designed for secure installation and dependable fastening. These compact inserts are ideal for 3D printed components, plastic boards, molded parts, and DIY projects where standard screws alone may not provide sufficient thread durability. The knurled exterior helps the insert grip surrounding material after installation, while the internal threaded brass inserts provide a practical connection point for compatible machine screws. Available in M2, M2.5, M3, M4, M5, and M6 sizes for a variety of projects.

Why Choose Our Brass Heat Set Threaded Insert Nuts

Threads formed directly in plastic can wear or strip after repeated fastening. These brass inserts reinforce the connection with durable internal metal threads, making them especially useful for projects that need to be assembled, serviced, or taken apart repeatedly.

Perfect For

Ideal for 3D printed enclosures, electronics housings, prototypes, plastic panels, robotics, DIY builds, model making, equipment repairs, and custom fabrication projects.

How to Use

Select an insert that matches your screw size and prepare a correctly sized opening in the plastic part. Heat and press the insert carefully into compatible thermoplastic material using an appropriate installation tool, keeping it aligned until securely seated.

Build Stronger Connections Into Your Projects

Upgrade plastic parts with durable brass threads and create cleaner, more serviceable fastening points for your next build.
